NCP1215A Low Cost Variable OFF Time Switched Mode Power Supply Controller

TSOP *6 4 3 1 2 6 5 7 8 SO *8 1 2 3 4 5 6 7 8 Symbol FB Description The FB pin provides voltage feedback loop. The current injected into the pin determines the primary switch OFF time interval. It also influences the peak value of the primary current. Connection for an external timing .

www.DataSheet4U.com NCP1215A Low Cost Variable OFF Time Switched Mode Power Supply Controller The NCP1215A 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. Also, when OFF Time expands, the peak current is gradually reduced down to approximately 1/4 of the .
