SS6578 Overview
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.
Key Features
- 4V to 18V input voltage operation
- High-efficiency (up to 95%)
- Low quiescent current at 90µA
- Pulse-skipping and pulse-frequency modulation
- Inputs-uncommitted current-sense comparator
