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 projects.

Peak current-mode control
Adjustable switching frequency up to 500 kHz, jittering frequency ±5% of the switching frequency
Latched primary overcurrent protection with 10ms fixed delay
Delay extended to 150ms in E-version
Adjustable soft−start timer
Auto−recovery brown−out detection
UC384X−like UVLO thresholds, Vcc range from 9V to 28V with auto−recovery UVLO
