AP4340 Datasheet (BCD Semiconductor) - DYNAMIC PSR ACCELERATOR

AP4340, DYNAMIC PSR ACCELERATOR

The AP4340 is an output voltage detector for Primary Side Control System.

It detects the output voltage and provides a periodical signal when the output voltage is lower than a certain threshold.

The periodical signal can be coupled by the transformer to the primary side and provided as an awakening
