EVLSRK1000B-TO

SRK1000B adaptive synchronous rectification controller for flyback converter demonstration board with STF80N10F7. This demonstration board is designed for evaluation of the SRK1000B synchronous rectification controller. The SRK1000B 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 applications and in fixed frequency (FF) mixed DCM-CCM applications. The board is provided with a setting suitable for QR applications. The board includes the SR MOSFET (TO-220FP package) and can be easily implemented into an existing converter to substitute rectifier diodes.
