NCP1252EDR2G Description

Short technical summary and product information.

The NCP1252EDR2G is a Current Mode PWM Controller from On Semiconductor, suitable for building reliable AC-DC switching supplies, particularly for ATX power supplies. It offers an adjustable switching frequency up to 500 kHz and operates within a wide Vcc range of 9 V to 28 V.

 

Key features include peak current mode control, latched primary over-current protection with a 10 ms fixed delay, and auto-recovery brown-out detection. The controller also provides an adjustable soft-start timer and internal leading-edge blanking. It is available in an 8-SOIC package, making it a space-saving solution for cost-sensitive projects.

 

This controller is designed for Flyback and Forward converter topologies. Its features make it ready for updated no-load regulation specifications, and it is suitable for applications such as power supplies for PC silver boxes and game adapters.
