TEA2164 - ST Microelectronics

TEA2164 SWITCH MODE POWER SUPPLY PRIMARY CIRCUIT

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 contro.
