General Description

The SS6578 is a high performance step-down DC/DC controller, designed to drive an external P-channel MOSFET to generate programmable output voltages.

Two main schemes of Pulse-Skipping and Pulse-Frequency Modulation are employed to maintain low quiescent current and high conversion efficiency under wide ranges of input voltage and loading condition.

The SS6578 delivers 10mA to 2A of output current with 87%~93% efficiency at APPLICATIONS • Notebook 5V/3.3V Main Power • Step-Down DC/DC Controller Modules.
