    MP6902 8-24V, 400kHz Fast Turn-off Intelligent Controller SOIC8

    The MPS MP6902 is a Fast Turn-off Intelligent Controller. It operates from a 8 V to 24 V input and switches at 400 kHz. It is supplied in a SOIC8 package.

    The MP6902 is a Low-Drop Diode Emulator IC for Flyback converters which combined with an external switch replaces Schottky rectification diodes for high efficiency.

    Design Notes

    • The PFC inductor must support the maximum duty cycle at the lowest line voltage, which is where saturation risk peaks.
    • High-voltage startup and X-capacitor discharge paths dominate no-load standby loss; verify them against the efficiency target.
    • Leakage inductance and the RCD clamp set the turn-off loss — snubber values are a thermal trade-off, not a fixed recipe.
    • Synchronous rectification timing must track the primary switching; a mistimed SR FET conducts through its body diode and fails hot.
