Product Summary

The MAX761CSA is a Step-Up DC-DC Converter. It 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 are Flash Memory Programming, PCMCIA Cards, Battery-Powered Applications, High-Efficiency DC-DC Converters.
