This video demonstrates some of the features and capabilities of the NCP1351ADAPGEVB evaluation board. The NCP1351ADAPGEVB evaluation board from ON Semiconductor 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 it’s 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. Understand how to set-up and measure results for this board to optimize efficiency.
