PT6930 Series 25 Watt 5V Input Dual Output Integraged Switching Regulator SLTS062A (Revised 6/30/2000) · Dual Outputs: +3.3V/2.5V +3.3V/1.5V +3.3V/1.8V · · · · · · · Patent pending on package assembly Adjustable Output Voltage Remote Sense (both outputs) Standby Function Over-T emperature Protection Soft-Start Internal Sequencing 23-pin ExcaliburTM Package The PT6930 is a new series of 25W dual output ISRs designed to power the latest generation DSP chips. Both output voltages are independently adjustable with external resistors. In addition, the second output voltage of the PT6931 can be selected for either 2.5V or 1.8V to accommodate the next generation of DSP chips. The internal power sequencing of both outputs meet the requirements of TI's `C6000 series DSPs.
