NCP1380
Quasi-Resonant
Current-Mode Controller for
High-Power Universal
Off-Line Supplies
The NCP1380 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.
To improve the safety in overload situations, the controller includes
an Over Power Protection (OPP) 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 stays latched for option A and C or enters
auto?recovery mode for option B and D.
Particularly well suited for adapter applications, the controller
