The NCP1250ASN65T1G from ON Semiconductor is a highly integrated PWM controller designed for offline power supplies. It operates in peak current mode control with a fixed switching frequency of 65 kHz. This device supports a wide supply voltage range from 8.8 V to 28 V.
Key features include internal and adjustable Over Power Protection (OPP), frequency foldback down to 26 kHz, and skip-cycle operation in light load conditions. It also incorporates internal ramp compensation, a fixed 4 ms soft-start, and 100 ms timer-based auto-recovery short-circuit protection. The controller offers frequency jittering for reduced EMI and an OVP input for improved robustness.
This IC is housed in a compact 6-TSOP (SOT-23-6 Thin) package, suitable for surface mount applications. Its design facilitates rugged and high-performance offline power supply solutions for various applications such as AC-DC converters for TVs, set-top boxes, printers, and offline adapters for notebooks and netbooks.
