NEW PRODUCT A Product Line of Diodes Incorporated AP4340S DYNAMIC PSR ACCELERATOR Description Pin Assignments The AP4340S is an output voltage detector for Primary Side Control System.
It is a low power loss solution.
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 AP4340S can effectively improve the transient performance of Primary Side Control System.
AP4340S will enable a discharge circuit when it detects the output v...
