MAX770MJA規(guī)格書詳情
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).
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
? 300kHz Switching Frequency
Applications
??? Palmtops/Handy-Terminals
??? High-Efficiency DC-DC Converters
??? Battery-Powered Applications
??? Positive LCD-Bias Generators
??? Portable Communicators
??? Flash Memory Programmers
