AP1551 Overview
The AP1551 is monolithic IC designed for dual channel step-down DC/DC converters, and own the ability of driving a 2A load each channel without additional transistor ponent. Due to reducing the number of external ponent, the board space can be saved easily. The external shutdown function can be controlled by logic level and then e into standby mode.
