AIC1576 Overview
Description
The AIC1576 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
- High Efficiency (up to 95%)
- Low Quiescent Current at 90µA
- Pulse-Skipping and Pulse-Frequency Modulation
- Inputs-Uncommitted Current Sense Comparator
- Duty Cycle Adjustable
- 90KHz to 280KHz Oscillator Frequency
- Power-Saving Shutdown Mode (8µA Typical)
- Push-Pull Driver Output
