Product Overview

Demonstration board is designed for evaluation of the SRK1001 synchronous rectification controller. The SRK1001 implements a control scheme specific for secondary-side synchronous rectification in flyback converters and provides high current gate drive outputs for driving N-channel power MOSFET. The device can operate both in quasi-resonant (QR) applications and in fixed frequency (FF) mixed DCM-CCM applications. The board is provided with a setting suitable for QR application. In order to use the DIS/SYNC pin functionality, the user has to remove the zero ohm resistor R9: the PCB already provides a NPN transistor connected to this pin for remote ON/OFF.
  • Synchronous rectifier for flyback converter with fixed turn-on and adaptive turnoff
  • VCC range from 3.5V to 32V
  • DVS sensing voltage is 185V AMR
  • Maximum frequency is 500KHz
  • Internal gate drive for N-channel MOSFET
  • FDPF190N15A (150V, 19mohm ) TO220FP SR MOSFET
