NCP1252 Current Mode PWM controller

ON Semiconductor introduces the NCP1252 Current Mode PWM controller for Forward and Flyback Applications .
The NCP1252 controller offers everything needed to build a ac−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.
Main features of the NCP1252 are : Peak Current Mode Control , Adjustable Switching Frequency up to 500 kHz , Jittering Frequency ±5% of the Switching Frequency , Latched Primary Over Current Protection with 10 ms Fixed Delay , Delayed Operation Upon Start−up via an Internal Fixed Timer , Adjustable Soft−start Timer , Auto−recovery Brown−Out Detection , Vcc Range from 9 V to 28 V with Auto−recovery UVLO , Adjustable Internal Ramp Compensation
The NCP1252 can be used in applications like : Power Supplies for PC Silver Boxes, Games Adapter , Flyback and Forward Converter
