The NCP1340B3D1R2G from ON Semiconductor is a highly integrated quasi-resonant flyback controller designed for high-performance off-line power converters. It features a proprietary valley-lockout circuitry for stable valley switching, transitioning to frequency foldback mode and quiet-skip mode for efficiency at light loads. This controller supports a wide VCC range from 9 V to 28 V and operates within a temperature range of -40°C to 125°C.
Key protective features include internal brownout detection, non-dissipative Over Power Protection (OPP), latched overvoltage protection, NTC-ready overtemperature protection, and line removal detection. The device also includes an integrated high-voltage startup circuit and X2 capacitor discharge capability, enabling no-load power consumption below 30 mW. It is available in a 9-SOIC surface mount package.
This controller is suitable for applications requiring efficient and robust power conversion. Its features like frequency foldback and skip mode contribute to increased efficiency at light loads, while integrated protection mechanisms enhance converter ruggedness.
