♦ 2.7V to 6V Input Voltage

The MAX749 LCD bias supply produces a variable

negative output voltage when powered by a +3V to +5V

supply. The MAX749 evaluation kit (EV kit) has a -8.0V

to -23.6V adjustable output voltage. This is the typical

range for driving the backplane of a liquid crystal dis-

play (LCD).

♦ -8.0V to -23.6V Adjustable Output Voltage

♦ 40mA Output Current with +5V Input

15mA Output Current with +3V Input

♦ Easy Interface to µP

Two pushbutton switches, located on the EV kit’s print-

ed circuit board, control the output voltage. One switch

connects to the CTRL pin and the other to the ADJ pin.

Logic signals from an external controller may be con-

nected to the board for optional output voltage control.

♦ Pushbutton Control of Output Voltage
