MP6920 8-24V, 300kHz Fast Turn-Off Intelligent Rectifier SOIC8E
The MPS MP6920 is a Fast Turn-Off Intelligent Rectifier. It operates from a 8 V to 24 V input and switches at 300 kHz. It is supplied in a SOIC8E package.
The MP6920 is a fast turn-off intelligent rectifier for Flyback converters that combines a 60V power switch that replaces diode rectifiers 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.
