NCP1253BSN65T1G Description

Short technical summary and product information.

The NCP1253BSN65T1G is a highly integrated PWM controller from ON Semiconductor, designed for rugged and high-performance offline power supplies. It operates in peak current mode control with a fixed switching frequency of 65 kHz. The controller features frequency foldback down to 26 kHz and skip-cycle operation in light load conditions to optimize efficiency.

 

Key electrical specifications include an operating voltage range of 8.8 V to 28 V and a duty cycle of 80%. It incorporates essential fault protection features such as current limiting, open loop, over voltage, and short circuit protection. The device also includes adjustable ramp compensation and an internally fixed 4 ms soft-start.

 

This PWM controller is housed in a compact 6-TSOP package, suitable for surface mount applications. Its typical applications include AC-DC converters for TVs, set-top boxes, printers, and offline adapters for notebooks and netbooks. The device also boasts extremely low no-load standby power.
