SS6578 Datasheet (Silicon) - HIGH EFFICIENCY STEP DOWN DC/DC CONTROLLER

SS6578, HIGH EFFICIENCY STEP DOWN DC/DC CONTROLLER

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
