Product Summary

The max761csa+ is a step-up switching regulator provides high efficiency over a wide range of load currents, delivering up to 150mA. A unique, current-limited pulse-frequency-modulated (PFM) control scheme gives the max761csa+ the benefits of pulse-width-modulated (PWM) converters (high efficiency with heavy loads), while using less than 110μA of supply current (vs. 2mA to 10mA for PWM converters). The result is high efficiency over a wide range of loads. The applications of the max761csa+ include Flash Memory Programming, PCMCIA Cards, Battery Powered, Applications, High-Efficiency DC-DC Converters.
