The EVLSRK1000A-TO is a demonstration board, designed for evaluation of the SRK1000A synchronous rectification controller.
The SRK1000A 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. To use in FF applications, a 100 pF capacitor needs to be added in C4. A 68 kΩ resistor (R5) is provided on the TON pin that fixes the blanking after the turn-on to about 0.8 μs.
The board includes the SR MOSFET (TO-220FP package) and can be easily implemented into an existing converter to substitute rectifier diodes.
