Maxim MAX77100EWL+T

Overview

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 less than 110µA of supply current (vs. 2mA to 10mA for PWM converters).

♦ 90% Efficiency for 10mA to 1A Load Currents ♦ Up to 15W Output Power ♦ 110µA Max Supply Current ♦ 5µA Max Shutdown Current ♦ 2V to 16.5V Input Range (MAX770/MAX771/MAX772) ♦ Internal Shunt Regulator for High Input Voltages (MAX773) ♦ Preset or Adjustable Output Voltages MAX770: 5V or Adjustable MAX771: 12V or Adjustable MAX772: 15V or Adjustable MAX773: 5V, 12V, 15V, or Adjustable ♦ Current-Limited PFM Control Scheme ♦ 300kHz Switching Frequency
