NCP1252DDR2G Description

Short technical summary and product information.

The ON Semiconductor NCP1252DDR2G is a current mode PWM controller designed for cost-effective and reliable AC-DC switching power supplies. It is suitable for forward and flyback converter topologies.

 

Key electrical specifications include an operating voltage range of 9V to 28V and an adjustable switching frequency up to 500 kHz. The device offers features such as peak current mode control, adjustable soft-start, auto-recovery brown-out detection, and latched primary over-current protection with a 10 ms fixed delay. It has a maximum duty cycle of 47.5% for D & E versions.

 

This controller is housed in a compact SOIC-8 package, making it a suitable choice for space-sensitive projects. The operating temperature range is -25°C to 125°C (TJ). Its fault protection includes current limiting, and control features encompass frequency control and soft start.

 

Typical applications include power supplies for PC silver boxes and game adapters. The NCP1252DDR2G is designed for surface mount mounting type.
