ONSEMI NCP1251BSN65T1G PWM Controller
The NCP1251 is a compact, high-performance current-mode PWM controller designed for offline power supplies such as adapters and TVs. Operating up to 28 V, it features fixed switching frequencies of 65 or 100 kHz, internal ramp compensation, and frequency foldback down to 26 kHz to optimize efficiency at light loads. Integrated over power protection (OPP) and over voltage protection (OVP) enhance robustness, while auto-recovery and latch options provide flexible fault handling. Its low startup current, EMI jittering, and regulation features make it suitable for low standby power and energy-efficient applications.
