The ON Semiconductor NCP1252APG is a current mode PWM controller designed for cost-effective and reliable AC-DC switching supplies, particularly for ATX power supplies. It supports both Flyback and Forward converter topologies.
Key electrical specifications include an operating voltage range of 9V to 28V, a maximum duty cycle of 48%, and an adjustable switching frequency up to 500 kHz. The controller features peak current mode control, latched primary over-current protection with a 10 ms fixed delay, and auto-recovery brown-out detection for enhanced safety.
This component is housed in an 8-PDIP package, suitable for through-hole mounting, and operates within an ambient temperature range of -25°C to 125°C (TJ). It also includes features like adjustable soft-start and frequency control.
Typical applications include power supplies for PC silver boxes and game adapters.
