描述
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 display (LCD).
Two pushbutton switches, located on the EV kit's printed 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 connected to the board for optional output voltage control.
