5V/12V/15V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Controllers

General Description The MAX770–MAX773 step-up switching controllers provide 90 efficiency over a 10mA to 1A load. A unique current-limited pulse-frequency-modulation (PFM) control scheme gives these devices the benefits of pulse-width-modulation (PWM) converters (high efficiency at heavy loads)
