General Description

The MAX1572 is a fixed-frequency, synchronous stepdown DC-to-DC converter to power low-voltage microprocessor/DSP cores in portable equipment requiring high efficiency in a limited PC board area. The features are optimized for high efficiency over a wide load range, small external component size, low output ripple, and excellent transient response.

Features

? Up to 97 Efficiency

? 2MHz PWM Switching

? 800mA Guaranteed Output Current

? Low 48μA Quiescent Current

? Power-Saving Modes: Pulse-Group, Pulse-Skip,

?? Forced-PWM Mode

? 0.75V to 2.5V Preset Output Range

?? (in 50mV Increments)

? Voltage-Positioning Load Transients

? 5mVP-P Output Ripple

? Tiny 2.2μH Inductor

? 10μF Ceramic Output Capacitor

? Low 0.1μA Shutdown Current

? No External Schottky Diode Required

? Soft-Start with Zero Inrush Current

? 170ms (min) RESET Output

? Small 12-Pin, 4mm x 4mm Thin QFN Package

Applications

?? Cell Phones and Smart Phones

?? PDAs, Palmtops, and Notebook Computers

?? MP3 and DVD Players

?? Digital Cameras and Camcorders

?? PCMCIA Cards

?? Hand-Held Instruments
