NCP1379
Quasi-Resonant
Current-Mode Controller for
High-Power Universal
Off-line Supplies
The NCP1379 hosts a high ? performance circuitry aimed to
powering quasi ? resonant converters. Capitalizing on a proprietary
valley ? lockout system, the controller shifts gears and reduces the
switching frequency as the power loading becomes lighter. This
results in a stable operation despite switching events always occurring
in the drain ? source valley. This system works down to the 4 th valley
and toggles to a variable frequency mode beyond, ensuring an

excellent standby power performance.
The controller includes an Over Power Protection circuit which
clamps the delivered power at high ? line. Safety ? wise, a fixed internal
timer relies on the feedback voltage to detect a fault. Once the timer
elapses, the controller stops and enters auto ? recovery mode, ensuring
a low duty ? cycle burst operation. To further improve the safety of the
power supply, the NCP1379 features a pin to implement a combined
brown ? out/overvoltage protection.
