Description
NIKO-SEM Synchronous Rectification Controller N3867V N3867P GENERAL .
The N3867 is a low cost, high efficiency, synchronous rectification controller that specifically designed for the synchronous rectification applicatio.
Features
* ▲High efficiency operating. ▲Decrease areas of heatsink or PCB. ▲Solved heat dissipation. ▲Sensitive current detecter(about 20mV) ▲Suited for discontinuous,QR or continuous
mode operation. ▲Auto frequency tracking with PWM
frequency. ▲Suited for fixed or variable frequency ▲SOIC-8 and DIP-8 package.
Applications
* of the Fly-back AC/DC PWM mode switching power supply. The N3867 is included a totem pole output ideally suited for driving a synchronous rectification power MOSFET. In the QR mode or discontinuous mode operating, the current detector properly turns off the synchronous rectification power MOSFET by
