Synchronous rectification technology introduction:

Synchronous rectification is a new technology that uses dedicated power MOSFETs with extremely low on-state resistance to replace rectifier diodes to reduce rectification losses. It can greatly improve the efficiency of DC / DC converters and there is no dead zone voltage caused by Schottky barrier voltage. The power MOSFET is a voltage-controlled device, and its volt-ampere characteristic is linear when it is turned on. When the power MOSFET is used as the rectifier, the gate voltage must be synchronized with the phase of the rectified voltage to complete the rectification function, so it is called synchronous rectification. Synchronous rectification technology is to greatly reduce the rectification loss of the output end of the switching power supply, thereby improving the conversion efficiency and reducing the heating of the power supply itself.
