MP163C Offline Regulator SOIC16
The MPS MP163C is a Offline Regulator. It is supplied in a SOIC16 package.
The MP163 is a primary-side regulator that provides accurate, dual-output, constant voltage (CV) regulation without an optocoupler.

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.
