NCP1351BDR2G - Brand New onsemi AC DC Converters, Offline Switchers
-
**The NCP1351 is a current−mode controller targeting low power off−line
flyback Switched Mode Power Supplies (SMPS) where cost is of utmost importance. Based on a fixed peak current technique (quasi−fixed TON), the controller decreases its switching frequency as the load becomes lighter. As a result, a power supply using the NCP1351 naturally offers excellent no−load power consumption, while optimizing the efficiency in other loading conditions. When the frequency decreases, the peak current is gradually reduced down to approximately 30% of the maximum peak current to prevent transformer mechanical resonance. The risk of acoustic noise is thus**
greatly diminished while keeping good standby power performance.
