Overview
FM9919B FM9920B is a high-performance secondary-side synchronous rectifier chip that integrates MOS with low on-resistance. Suitable for isolated synchronous rectification applications,
It is especially suitable for occasions where high efficiency is required in chargers. The FM9920B is used in a 5V flyback controlled switching power supply system to replace
Secondary Schottky. FM9919B FM9920B can effectively reduce the power loss of the secondary rectifier tube, improve the efficiency of the system, and provide customers with cost-effective solutions.
