SC1578 Overview
Description
The SC1578 is a high performance step-down DC-DC converter, designed to drive an external P-channel MOSFET to generate programmable output voltages. Two main schemes of pulse-skipping and pulsefrequency modulation are employed to maintain low quiescent current and high conversion efficiency over wide ranges of input voltage and loads.
Key Features
- 4V to 24V input voltage operation
- High efficiency (up to 95%)
- Low quiescent current at 90µA
- Pulse-skipping and pulse-frequency modulation
- Inputs-uncommitted current sense comparator
