DESCRIPTION
In amasterslavearchitecture,theTEA2164control
IC achieves the slave function.Primarily designed
for TV receivers and monitors applications, this
circuit providesaneasy synchronizationand smart
solutionfor low power stand by operation.
Located at the primary side the TEA2164 Control
IC ensures:
- the powersupply start-up
- the power supply control under stand-by condi-
tions
- the processof the regulation signals sent by the
mastercircuit located at the secondaryside
- directbasedrive ofthebipolarswitchingtransistor
- the protection of the transistor and the power
supplyunder abnormalconditions.
For more details, refer to applicationnote AN409.
