EVLSRK1000-PF

SRK1000 adaptive synchronous rectification controller for flyback converter demonstration board with logic level SR MOSFET. This demonstration board is designed for evaluation of the SRK1000 synchronous rectification controller. The SRK1000 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 includes the SR MOSFET (PowerFLAT 5 x 6 package) and can be easily implemented into an existing converter to substitute rectifier diodes.
