The NCP1380 is a high performance device designed to power quasi-resonant converters. The controller is based on a proprietary valley lockout system that switches and reduces switching frequency when the power load becomes lighter. This will result in stable operation even under switching events that are always triggered in the drain-source valley. The system can operate down to the 4th valley and then switch to variable frequency mode, ensuring excellent standby power performance. For increased safety during overload conditions, the controller includes an Over Power Protection (OPP) circuit that clamps the power supplied at the high line. A fixed internal timer with safety features relies on the feedback voltage to detect faults. Once the timer expires, the controller stops and remains latched for options A and C, or enters auto-recovery mode for options B and D. Especially suited for adapter applications, the controller has a pin to implement combined overvoltage/high temperature protection (versions A and B) or combined undervoltage/overvoltage protection (versions C and D).
