  • The EVLSRK1000-DP is a demonstration board, 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 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 (DPAK package) and can be easily implemented into an existing converter to substitute rectifier diodes.

    Key Features

    • Synchronous rectifier for flyback converter, with fixed turn-on and adaptive turn-off
    • VCC range: 3.5 V to 32 V
    • DVS max. operating voltage 90 V
    • Max. frequency: 500 kHz
    • Internal gate-drive for N-channel MOSFET
    • SR MOSFET type: STD80N10F7 (100 V - 10 mΩ) DPAK
