STMicroelectronics SRK1004BTR, Synchronous 500 kHz 6-Pin, DFN

The STMicroelectronics Synchronous rectifier controller is intended for secondary side synchronous rectification in Non Complementary Actively Clamped Flyback, Resonant Flyback, and Quasi Resonant Flyback converters. It provides a gate drive output suitable for N channel logic level or standard level power MOSFETs. The control scheme of this device is such that the SR MOSFET is switched on as soon as current starts flowing through its body diode and it is then switched off as current approaches zero.

Able to operate in both low side and high side configuration
High voltage sensing input for SR MOSFET drain source voltage
Operating frequency up to 500 kHz
Fast short circuit detector
Tiny DFN 6L 2x2 mm package
