The NCP1250BSN100T1G from ON Semiconductor is a highly integrated PWM controller designed for rugged and high-performance offline power supplies. It operates in peak current mode control with a fixed switching frequency of 100 kHz, featuring frequency foldback down to 26 kHz and skip-cycle operation in light load conditions. The controller supports a supply voltage range of 8.8 V to 28 V and includes internal ramp compensation and a fixed 4 ms soft-start.
Protection features are robust, including internal and adjustable over power protection (OPP), an over voltage protection (OVP) input, and a 100 ms timer-based auto-recovery short-circuit protection. The device also offers frequency jittering for reduced EMI. It is available in a compact 6-TSOP (SOT-23-6 Thin) package, suitable for surface mount applications.
Typical applications include AC-DC converters for TVs, set-top boxes, printers, and offline adapters for notebooks and netbooks. The controller is designed for efficiency, with less than 100 mW standby power at high line, and is EPS 2.0 compliant.
