AIC1578 High-Efficiency, Step-Down DC/DC Converter FEATURES • 4V to 20V Input Voltage Operation. • 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. DESCRIPTION The AIC1578 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 PulseSkipping and Pulse-Frequency Modulation are employed to maintain low quiescent current and high conversion efficiency under wide ranges of input voltage and loading condition.
