General 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.

Key Features

  • : - maximum output power 140W (transistor forced gain : 3.5) Figure 2 : Master Slave Power Supply Architecture - stand-by mode output power (1W ≤ Psb ≤ 6W ; efficiency > 50%) - operating frequency up to 50kHz - power-switch : bipolar transistor Adapted master-circuit : Monitor.
