Overview

Current Mode PWM Controller for Forward and Flyback Applications NCP1252 The NCP1252 controller offers everything needed to build cost− effective and reliable 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.
Finally a SOIC−8 package saves PCB space and represents a solution of choice in cost sensitive project.
Features  Peak Current Mode Control  Adjustable Switching Frequency up to 500 kHz  Jittering Frequency 5% of the Switching Frequency  Latched Primary Over ...
