Product Summary

The NCP1215ADR2G is a controller for low power off-line flyback Switched Mode Power Supplies (SMPS) featuring low size, weight and cost constraints together with a good low standby power performance. The operating principle uses switching frequency reduction at light load by increasing the OFF Time. The typical applictions of the NCP1215ADR2G include Auxiliary Power Supply, Standby Power Supply, AC-DC Adapter and Off-line Battery Charger.
