TEA2164S

SWITCH MODE POWER SUPPLY PRIMARY CIRCUIT

STMicroelectronics 

TEA2164S

I - FIELD OF APPLICATION

The TEA2164S control circuit has been designed

primarily for discontinuous mode flyback built with

a master-slave architecture, whatever the field of

application.

But due to its capability to synchronize the transis-

tor switching-off with an external signal (line fly-

back) and due to an adaptedburst-mode operation

for a low power stand-by operation, the TEA2164

offers a smart solution for monitors and TV sets

applications.

Power supply main features :

- maximum output power 140W (transistor forced

gain : 3.5)

R

- stand-by mode output power (1W ≤ Psb ≤ 6W ;

efficiency > 50%)

- operating frequency up to 50kHz

- power-switch : bipolar transistor

Adapted master-circuit :

- Monitor application

- Standard TV application

- Digital TV application
