MAX771MJA规格书详情
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), while using less than 110µA of supply current (vs. 2mA to 10mA for PWM converters).
特性 Features
♦ 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
