Product Overview
The MAX749 generates negative LCD-bias contrast voltages from 2V to 6V inputs. Full-scale output voltage can be scaled to -100V or greater, and is digitally adjustable in 64 equal steps by an internal digital-toanalog converter (DAC). Only seven small surfacemount components are required to build a complete supply. The output voltage can also be adjusted using a PWM signal or a potentiometer.
- +2.0V to +6.0V Input Voltage Range
- Flexible Control of Output Voltage:
- Digital Control
- Potentiometer Adjustment
- PWM Control
- Output Voltage Range Set by One Resistor
- Low, 60µA Max Quiescent Current
- 15µA Max Shutdown Mode
