The EVLSRK1000B-TO is a demonstration board, 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. 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. https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2020-06-05 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2021-04-02 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2021-07-15 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2021-12-07 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2022-04-10 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2022-06-12 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2022-06-24 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2023-03-26 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2023-07-18 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2024-01-01 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2024-07-05 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2024-08-18 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2024-12-19 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2025-03-12 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2025-04-18 https://elecena.pl/product/16949132/evlsrk1000b-to-srk1000b-adaptive-synchronous-rectification-controller-for-flyback 2025-06-27
