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.
