MAX770 - 5V/12V/15V or Adjustable / High-Efficiency / Low IQ / Step-Up DC-DC Controllers
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), while using le
