NCP1343 Quasi-Resonant Flyback Controllers

onsemi NCP1343 Quasi-Resonant Flyback Controllers are ideal for designing high-performance off-line power converters. The NCP1343 features a proprietary valley-lockout circuitry, that ensures stable valley switching. This system works down to the 6th valley and transitions to frequency foldback mode to reduce switching losses. The NCP1343 enters quiet-skip mode as the load decreases to manage the power delivery while minimizing acoustic noise.
