Product Summary

The MAX762CSA is a step-up switching regulator. The device 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 MAX762CSA 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 MAX762CSA input voltage range is 2V to 16.5V. Output voltages are preset to 15V, or the device can be set with two external resistors. With a 5V input, the MAX762CSA guarantees a 12V, 150mA output. Its high efficiency, low supply current, fast start-up time, SHDN controlling capability, and small size make the MAX762CSA ideal for powering flash memory.
