The NCP1342AMDCDAD1R2G from ON Semiconductor is a highly integrated quasi-resonant flyback controller designed for high-performance off-line power converters. It operates with an input voltage range of 9V to 28V and supports a switching frequency between 25kHz and 500kHz.
This controller features a proprietary valley-lockout circuitry for stable valley switching and transitions to frequency foldback mode to reduce switching losses. It also incorporates Rapid Frequency Foldback and Quiet-Skip mode for efficient light load performance. Protective features include brownout detection, non-dissipative Over Power Protection (OPP), latched overvoltage protection, and NTC-ready overtemperature protection.
The NCP1342AMDCDAD1R2G is supplied in a 9-SOIC package suitable for surface mounting. Its design enables low no-load power consumption, making it suitable for energy-efficient power supply designs.
Key specifications include a wide VCC range, integrated X2 capacitor discharge capability, and abnormal overcurrent fault protection. The device also includes a 4ms soft-start timer for controlled power-up sequences.
