NCP1252ADR2G - ON Semiconductor Function Overview

The NCP1252ADR2G is a current-mode Pulse Width Modulation (PWM) Controller for forward and flyback applications. It offers everything needed to build cost- effective and reliable AC to DC switching supplies dedicated to ATX power supplies. Thanks to the use of an internally fixed timer, NCP1252 detects an output overload without relying on the auxiliary Vcc. A Brown-Out input offers protection against low input voltages and improves the converter safety.
Peak current mode control
Jittering frequency ±5% of the switching frequency
Adjustable soft-start timer
Auto-recovery brown-out detection
Internal 160ns Leading edge blanking
Adjustable internal ramp compensation
Ready for updated no load regulation specifications
