MAXIM INTEGRATED / ANALOG DEVICES MAX749CSA LCD Bias Supply
The MAX749 is a digitally adjustable LCD bias supply designed to generate negative bias voltages from 2V to 6V inputs. It offers flexible control options including digital, potentiometer, and PWM adjustments, with an output range adjustable up to -100V or more. Its high switching frequency (up to 500kHz), low quiescent current (60μA max), and current-limited control scheme ensure high efficiency and minimal external components. Suitable for portable and computing devices, it drives external P-channel MOSFETs or PNP transistors for reliable LCD contrast biasing.
