FEATURES
o Up to 94% Efficiency o 0.7V to 5.5V Input Range o Up to 800mA Output o Fixed 3.3V Output (or adj from 2.5V to 5.5V) o PWM Synchronous Rectified Topology o Low-Noise, Constant Frequency Operation (1MHz) o 0.1µA Logic-Controlled Shutdown o Synchronizable Switching Frequency o Adjustable Current Limit o Adjustable Soft-Start o 10-Pin µMAX Package GENERAL DESCRIPTION
Small external components and a tiny 10-pin µMAX package make this device an excellent choice for small hand-held applications requiring the longest possible battery life. Maxim's proprietary IdleMode™ circuitry significantly improves efficiency at light load currents while smoothly transitioning to fixedfrequency PWM operation at higher load currents to maintain excellent full-load efficiency. Low-noise, forced PWM mode is available for applications requiring constant-frequency operation at all load currents. The MAX1760 may also be synchronized to an external clock to protect sensitive frequency bands in communications equipment.
