NCP1252  
Current Mode PWM  
Controller for Forward and  
Flyback Applications  
The NCP1252 controller offers everything needed to build cost  
effective and reliable acdc 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 BrownOut input offers protection against low input voltages  
and improves the converter safety. Finally a SOIC8 package saves  
PCB space and represents a solution of choice in cost sensitive project.
