NCP1250BP65G Description

Short technical summary and product information.

The ON Semiconductor NCP1250BP65G is a highly integrated PWM controller suitable for offline power supplies. It features a fixed-frequency, current-mode control operation at 65 kHz. The 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. Frequency jittering is included for normal and frequency foldback modes, with an option for auto-recovery or latched short-circuit protection. An OVP input enhances robustness.

 

This controller is available in an 8-PDIP package and is designed for through-hole mounting. It operates within a temperature range of -40°C to 125°C (TJ) and has a duty cycle of 80%. The topology is Flyback with isolated output.

 

Typical applications include AC-DC converters for TVs, set-top boxes, and printers, as well as offline adapters for notebooks and netbooks.
