LED Regulated Power Module DC-DC 15A
Introduction to Synchronous Rectification Technology:
Synchronous rectification is a new technology that uses power MOSFETs with extremely low on state resistance to replace rectifier diodes and 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. Power MOSFETs belong to voltage controlled devices, and their volt ampere characteristics exhibit a linear relationship during conduction. When using power MOSFETs as rectifiers, it is required to maintain synchronization between the gate voltage and the phase of the rectified voltage in order to complete the rectification function, hence it is called synchronous rectification. Synchronous rectification technology greatly reduces the rectification loss at the output end of the switching power supply, thereby converting efficiency and reducing the heating of the power supply itself.
Module Parameters:
● Module nature: Non isolated buck module (BUCK) synchronous rectification
● Input voltage: 4-32V, please reserve the voltage margin.
