MAX1771ESA+ General Description
The MAX1771 step-up switching controller provides 90% efficiency over a 30mA to 2A load. A unique current-limited pulse-frequency-modulation (PFM) control scheme gives this device 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 30mA to 2A Load Currents
- Up to 24W Output Power
- 110µA (max) Supply Current
- 5µA (max) Shutdown Current
- 2V to 16.5V Input Range
- Preset 12V or Adjustable Output Voltage

- Up to 300kHz Switching Frequency
- Evaluation Kit Available
Application
- Battery-Powered Applications
- Flash Memory Programming
- High-Power RF Power-Amplifier Supply
- Palmtops/Handheld Terminals
- Portable Communicators
- Positive LCD-Bias Generators
