The NCP1343BADBDEAD1R2G from On Semiconductor is a sophisticated quasi-resonant flyback controller designed for high-performance off-line power converters. It integrates a proprietary valley-lockout circuitry for stable valley switching, transitioning to frequency foldback mode to minimize switching losses. At lower loads, it enters quiet-skip mode for efficient power delivery with reduced acoustic noise.
Key features include integrated high-voltage startup with brownout detection, a wide VCC range of 9V to 28V, and comprehensive fault protection including overvoltage, overcurrent, and overtemperature detection. The controller supports valley switching operation with valley-lockout for noise-free performance and incorporates rapid frequency foldback with a minimum frequency clamp of 25 kHz for improved light-load efficiency. It also features skip mode with quiet-skip technology and frequency jittering for reduced EMI.
This controller is suitable for applications requiring high transient load capability due to its power excursion mode (PEM). It is supplied in a 9-SOIC package and operates within an ambient temperature range of -40°C to 125°C (TJ). The device is surface-mount compatible.
Designed for ruggedness and efficiency, the NCP1343BADBDEAD1R2G is an excellent choice for power supply designs where stable operation, fault tolerance, and optimized performance across various load conditions are critical.
