1 / 13 page Preliminary Datasheet DYNAMIC PSR ACCELERATOR AP4340 Aug. 2011 Rev. 1. 1 BCD Semiconductor Manufacturing Limited 1 General Description 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 signal for the main primary side controller. By fast response to secondary side voltage, the AP4340 can effectively improve the transient performance of Primary Side Control System. The AP4340 is available in TO-92 and SOT-23 packages. Features • Fast Detector of Supply Voltages • 37kHz Output Pulse • No External Components Applications · Adapters/Chargers for Cell/Cordless Phones, ADSL Modems, MP3 and Other Portable Apparatus · Standby and Auxiliary Power Supplies TO-92 (Bulk Packing) TO-92 (Ammo Packing) SOT-23 Figure 1.
