Description

General part information

NCP1252 Series

The NCP1252 controller offers everything needed to build cost effective and reliable ac-dc switching supplies dedicated to ATX power supplies or any forward application. 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, the SOIC-8 package saves PCB space and represents a solution of choice in cost sensitive project.
