The NCP1342AMDCDD1R2G from On Semiconductor is a highly integrated quasi-resonant flyback controller designed for high-performance off-line power converters. It supports a wide operating voltage range from 9V to 28V and offers adjustable overpower protection.
Key features include valley switching operation with valley-lockout for noise-free performance, frequency foldback with a minimum frequency clamp of 25 kHz for improved light load efficiency, and rapid frequency foldback for quick switching frequency reduction. The controller also incorporates skip mode with quiet-skip technology for optimal light load performance and minimized current consumption, enabling no-load power consumption below 30 mW.
This device includes integrated high-voltage startup circuitry with brownout detection and an integrated X2 capacitor discharge capability. Protective features such as overvoltage protection, abnormal overcurrent fault protection, internal temperature shutdown, and adjustable overpower protection enhance converter ruggedness. The NCP1342AMDCDD1R2G is supplied in a 9-SOIC package suitable for surface mounting.
Its design considerations include frequency jittering for reduced EMI signature and a 4 ms soft-start timer. The controller is suitable for applications requiring efficient and reliable power conversion.
