NCP1252
Current Mode PWM
Controller for Forward and
Flyback Applications
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.
