The NCP1343BADBDEAD1R2G quasi-resonant flyback controller is ideal for designing high-performance off-line power converters. The NCP1343 features a proprietary valley locking circuit that ensures stable valley switching. The system can operate at values as low as sixth valley and switch to frequency reentry mode to reduce switching losses. With reduced load, the NCP1343 can enter a quiet jump mode to manage power output while minimizing noise.
