NCP1256BSN65T1G Description

Short technical summary and product information.

The ON Semiconductor NCP1256BSN65T1G is a versatile offline PWM current mode controller suitable for switch mode power supplies ranging from a few watts up to several tens of watts. Housed in a compact SOT-23-6 (TSOP-6) package, this controller operates at a fixed frequency of 65 kHz and incorporates peak current mode control.

 

Key features include adjustable brown-out and over-power protection circuits, along with frequency foldback down to 26 kHz and skip-cycle operation in light load conditions. It also provides a 70 ms timer-based auto-recovery short circuit protection and latched/auto-recovery OVP protection on Vcc. The device offers a drive capability of +500 mA / -500 mA.

 

This controller is ideal for applications such as AC-DC adapters for portable devices, computers, and tablets, contributing to cost-effective and efficient power solutions. Its robust protection features enhance system reliability.
