Product Details
__
[ ON-Semiconductor ]
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 SOIC8 package saves PCB space and represents a solution of choice in cost sensitive project.
