Product Overview

Demonstration board 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. To use in FF applications, a 100pF capacitor needs to be added in C3. The board includes the SR MOSFET (PowFLAT 5 x 6 package) and can be easily implemented into an existing converter to substitute rectifier diodes.
  • Synchronous rectifier for flyback converter with fixed turn-on and adaptive turnoff
  • VCC range from 3.5V to 32V
  • DVS sensing voltage of 185V AMR
  • Maximum frequency of 500KHz
  • Internal gate drive for N-channel MOSFET
  • SR MOSFET type (BSC110N15NS5 standard level (150V - 11mohm) PowerFLAT 5 x 6
