TEA2164 SWITCH MODE POWER SUPPLY PRIMARY CIRCUIT . . . . . . . POSITIVE AND NEGATIVE OUTPUT CURRENT UP TO 1.2A AND ­ 1.7A A TWO LEVEL COLLECTOR CURRENT LIMITATION COMPLETE TURN OFF AFTER LONG DURATION OVERLOADS UNDER AND OVER VOLTAGE LOCK-OUT SOFT START BY PROGRESSIVE CURRENT LIMITATION DOUBLE PULSE SUPPRESSION BURST MODE OPERATION UNDER STANDBY CONDITIONS DESCRIPTION In a master slave architecture, the TEA2164 control IC achieves the slave function. Primarily designed for TV receivers and monitors applications, this circuit provides an easy synchronization and smart solution for low power stand by operation. Located at the primary side the TEA2164 Control IC ensures : - the power supply start-up - the power supply control under stand-by conditions - the process of the regulation signals sent by the master circuit located at the secondary side - directbase drive of the bipolar switching transistor - the protection of the transistor and the power supply under abnormal conditions. For more details, refer to application note AN409.
