MAX761 - Maxim

MAX761 12V/15V or Adjustable / High-Efficiency / Low IQ / Step-Up DC-DC Converters

The MAX761/MAX762 step-up switching regulators provide 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 devices the benefits of pulse-width-modulated (PWM) converters (high efficiency with heavy loads), while using less than 110µA of supply current (.
