GreenChipTMII SMPS control IC
GENERAL DESCRIPTION The GreenChipTMII is the second generation of green Switched Mode Power Supply (SMPS) controller ICs operating directly from the rectified universal mains. A high level of integration leads to a cost effective power supply with a very low number of external components. The special built-in green functions allow the efficiency to be optimum at all power levels. This holds for quasi-resonant operation at high power levels, as well as fixed frequency operation with valley switching at medium power levels. At low power (standby) levels, the system operates at reduced frequency and with valley detection. ORDERING INFORMATION TYPE NUMBER TEA1507P PACKAGE NAME DIP8 DESCRIPTION plastic dual in-line package; 8 leads (300 mil)
TEA1507
If burst mode operation is applied, the standby power level can even be reduced to below 1 W. The proprietary high voltage BCD800 process makes direct start-up possible from the rectified mains voltage in an effective and green way. A second low voltage BICMOS IC is used for accurate, high speed protection functions and control. Highly efficient, reliable supplies can easily be designed using the GreenChipTMII controller.

FUNCTIONAL DESCRIPTION The TEA1507 is the controller of a compact flyback converter, with the IC situated at the primary side. An auxiliary winding of the transformer provides demagnetization detection and powers the IC after start-up. The TEA1507 operates in multi modes. The next converter stroke is started only after demagnetization of the transformer current (zero current switching), while the drain voltage has reached the lowest voltage to prevent switching losses (green function). The primary resonant circuit of primary inductance and drain capacitor ensures this quasi-resonant operation. The design can be optimized in such a way that zero voltage switching can be reached over almost the universal mains range. To prevent very high frequency operation at lower loads, the quasi-resonant operation changes smoothly in fixed frequency PWM control. At very low power (standby) levels, the frequency is controlled down, via the VCO, to a minimum frequency of about 6 kHz. Typically, 3 Watts can be achieved for a 75 W converter with an output power of 100 mW. Start-up, mains enabling operation level and undervoltage lock out (see Figs. 10 and 11) Initially, the IC is self supplying from the rectified mains voltage via pin DRAIN. Supply capacitor CVCC is charged by the internal start-up current source to a level of about 4 V or higher, depending on the drain voltage. Once the drain voltage exceeds the M-level (mains-dependent operation-enabling level), the start-up current source will
continue charging capacitor CVCC (switch S1 will be opened), see Fig.2. The IC will activate the power converter as soon as the voltage on pin VCC passes the VCC(start) level. The IC supply is taken over by the auxiliary winding as soon as the output voltage reaches its intended level and the IC supply from the mains voltage is subsequently stopped for high efficiency operation (green function). The moment the voltage on pin VCC drops below the VUVLO (undervoltage lock out) level, the IC stops switching and enters a safe restart from the rectified mains voltage. Inhibiting the auxiliary supply by external means causes the converter to operate in a stable, well-defined burst mode. Supply management All (internal) reference voltages are derived from a temperature compensated, on-chip band gap circuit.

GreenChipTMII SMPS control IC
Current mode control Current mode control is used for its good line regulation behaviour. The `on-time' is controlled by the internally inverted control pin voltage, which is compared with the primary current information. The primary current is sensed across an external resistor. The driver output is latched in the logic, preventing multiple switch-on. The internal control voltage is inversely proportional to the external control pin voltage, with an offset of 1.5 V. This means that a voltage range from 1 to 1.5 V on pin CTRL will result in an internal control voltage range from 0.5 to 0 V (the maximum external control voltage results in a minimum duty cycle). Oscillator The maximum fixed frequency of the oscillator is set by an internal current source and capacitor. The maximum frequency is reduced once the control voltage enters the VCO control window. Then, the maximum frequency changes linearly with the control voltage until the minimum frequency is reached (see Figs 5 and 6). Valley switching (see Fig.7) A new cycle starts when the power switch is switched on. After the `on-time' (which is determined by the `sense' voltage and the internal control voltage), the switch is opened and the secondary stroke starts. After the secondary stroke, the drain voltage shows an oscillation 1 with a frequency of approximately --------------------------------------------------( 2 × × ( Lp × Cd ) ) where Lp is the primary self inductance of the transformer and Cd is the capacitance on the drain node.
TEA1507
As soon as the oscillator voltage is high again and the secondary stroke has ended, the circuit waits for the lowest drain voltage before starting a new primary stroke. This method is called valley detection. Figure 7 shows the drain voltage together with the valley signal, the signal indicating the secondary stroke and the oscillator signal. In an optimum design, the reflected secondary voltage on the primary side will force the drain voltage to zero. Thus, zero voltage switching is very possible, preventing large 1 2 capacitive switching losses P = -- × C × V × f , and 2 allowing high frequency operation, which results in small and cost effective inductors. Demagnetization The system will be in discontinuous conduction mode all the time. The oscillator will not start a new primary stroke until the secondary stroke has ended. Demagnetization features a cycle-by-cycle output short-circuit protection by immediately lowering the frequency (longer off-time), thereby reducing the power level. Demagnetization recognition is suppressed during the first tsuppr time. This suppression may be necessary in applications where the transformer has a large leakage inductance and at low output voltages/start-up. Minimum and maximum `on-time' The minimum `on-time' of the SMPS is determined by the Leading Edge Blanking (LEB) time. The IC limits the `on-time' to 50 µs. When the system desires an `on-time' longer than 50 µs, a fault condition is assumed (e.g. removed Ci), the IC will stop switching and enter the safe restart mode.

OverVoltage Protection (OVP) An OVP mode is implemented in the GreenChipTM series. For the TEA1507, this works by sensing the auxiliary voltage via the current flowing into pin DEM during the secondary stroke. The auxiliary winding voltage is a well-defined replica of the output voltage. Any voltage spikes are averaged by an internal filter. If the output voltage exceeds the OVP trip level, the OVP circuit switches the power MOSFET off. Next, the controller waits until the UVLO level is reached on pin VCC. This is followed by a safe restart cycle, after which switching starts again. This process is repeated as long as the OVP condition exists. The output voltage at which the OVP function trips, Vo(OVP) can be set by the demagnetization resistor, RDEM: Ns V o ( OVP ) = ----------- × ( I (OVP)(DEM) × R DEM + V clamp ( DEM ) ( pos ) ) N aux Where Ns is the number of secondary turns and Naux is the number of auxiliary turns of the transformer. Current Iref is internally trimmed. The value of the demagnetization resistor (RDEM) can be adjusted to the turns ratio of the transformer, thus making an accurate OVP possible. OverCurrent Protection (OCP) The cycle-by-cycle peak drain current limit circuit uses the external source resistor to measure the current accurately. This allows optimum size determination of the transformer core (cost issue). The circuit is activated after the leading edge blanking time, tleb. The OCP protection circuit limits the `sense' voltage to an internal level. OverPower Protection (OPP) During the primary stroke, the rectified mains input voltage is measured by sensing the current drawn from pin DEM. This current is dependent on the mains voltage, according V aux N × V mains to the following formula: I ( DEM ) -------------- -------------------------R DEM R DEM N aux Where: N = ----------Np The current information is used to adjust the peak drain current, which is measured via pin Isense. The internal compensation is such that an almost mains independent maximum output power can be realized. The OPP curve is given in Fig.8. 2000 Dec 05 8

Short winding protection After the leading edge blanking time, the short winding protection circuit is also activated. If the `sense' voltage exceeds the short winding protection voltage Vswp, the converter will stop switching. Once VCC drops below the UVLO level, capacitor CVCC will be recharged and the supply will restart again. This cycle will be repeated until the short circuit is removed (safe restart mode). The short winding protection will also protect in case of a secondary diode short circuit. Overtemperature protection An accurate temperature protection is provided in the circuit. When the junction temperature exceeds the thermal shutdown temperature, the IC will stop switching. When VCC drops to UVLO, capacitor CVCC will be recharged to the Vstart level. If the temperature is still too high, VCC will drop again to the UVLO level, etc. (safe restart mode). Operation recommences when the junction temperature drops 8 degrees typically.

Burst mode standby Pin CTRL (pin 3) is also used to implement the burst mode standby. In burst mode standby, the power supply enters a special low dissipation state, where it typically consumes less than 1 W of input power (Po < 100 mW), but is still able to supply a microprocessor, for example. Figure 12 shows a flyback converter using the burst mode standby function. The system enters burst mode standby when the microprocessor closes switches S2 and S3 on the secondary side. Switch S2 connects the high voltage output secondary winding to the low voltage microprocessor capacitor (CµC), bypassing Co. When the voltage on CµC exceeds the Zener voltage, the opto-coupler is activated, sending a large current signal to CTRL. In response to this signal, the IC stops switching and enters a `hiccup' mode. This burst activation signal should be present for longer than the `burst blank' period (typically 30 µs): the blanking time prevents false burst triggering due to spikes. Figure 11 shows the burst-mode standby signals. The hiccup mode during burst mode standby operation does not differ from the hiccup mode in safe-restart mode during a system fault condition (e.g. OVP or output short circuit). The power is reduced during soft-restart mode. Burst mode standby operation continues until the microcontroller opens switches S2 and S3. The system then enters the start-up sequence and begins normal switching behaviour. V th I burstmode = ---------------- + I th ( on ) R CTRL (For burst mode specification, see Figs 11 and 12.) Soft start-up (pin Isense) To prevent transformer rattle during hiccup, the transformer peak current is slowly increased by the soft start function. This can be achieved by inserting a resistor and a capacitor between pin Isense (pin 5) and the sense resistor. An internal current source charges the capacitor to V = Iss × Rss, with a maximum of about 0.5 V. The start level and the time constant of the increasing primary current level can be adjusted externally by changing the values of Rss and Css. Driver V ocp ( I ss × R ss ) I primary(max) = ------------------------------------------R sense = R ss × C ss
TEA1507
The charging current Iss will flow as long as the voltage on pin Isense is below approximately 0.5 V. If the voltage on pin Isense exceeds the 0.5 V, the soft start current source will start limiting the current Iss. At the VCC(start) level, the Iss current source is completely switched off (see Fig.9). Since the soft start current Iss is subtracted from pin VCC charging current, the Rss value will affect the VCC charging current level by a maximum of 60 µA (typical value).

The driver circuit to the gate of the power MOSFET has a current sourcing capability of typically 125 mA and a current sink capability of typical 540 mA. This permits fast turn-on and turn-off of the power MOSFET for efficient operation. A low driver source current has been chosen to limit the V/t at switch-on. This reduces Electro Magnetic Interference (EMI) and also limits the current spikes across Rsense.

SOLDERING Introduction to soldering through-hole mount packages This text gives a brief insight to wave, dip and manual soldering. A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). Wave soldering is the preferred method for mounting of through-hole mount IC packages on a printed-circuit board. Soldering by dipping or by solder wave The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the joints for more than 5 seconds.
TEA1507
The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg(max)). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. Manual soldering Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds.
