SR Controller
The secondary synchronous rectification uses a low RDSon power MOSFET to replace the rectifier diode to reduce losses. The pre-detection working mode enables the rectifier MOSFET to have zero-voltage turn on and zero-current turn off features, which are used to improve the conversion efficiency of the power system and meet the need of high power density and miniaturization.
