The AP1501 series are monolithic IC that design for a step-down DC/DC converter, and own the ability of driving a 3A load without additional transistor component. Due to reducing the number of external component, the board space can be saved easily.
Features
-Output voltage: 3.3V, 5V, 12V and adjustable output version
-Adjustable version output voltage range, 1.23V to 37V+4%
