General Description

The MAX17108 evaluation kit (EV kit) is a fully assem-

bled and tested surface-mount PCB that evaluates the

MAX17108 10-channel, high-voltage level-shifting scan

driver for active-matrix, thin-film transistor (TFT) liquid-

crystal display (LCD) applications.

The EV kit operates from a DC supply voltage of +6V to

+20V for the MAX17108 AVDD input. The EV kit also

requires a +12V to +38V power supply and a -14V to

-4V negative power supply for the MAX17108 level-

shifting scan-driver circuitry. A PCB pad is provided to

monitor the output of an independent op amp, which is

configured to half the AVDD input voltage and is capa-

ble of providing up to 200mA of short-circuit current.

Features

o +6V to +20V AVDD Input Voltage Range

o +12V to +38V GON_ Input Voltage Range

o -14V to -4V GOFF Input Voltage Range

o Resistor-Adjustable LDO Regulator for Logic

Inputs

o Demonstrates 10 High-Voltage Level-Shifting

Scan Drivers

o Lead-Free and RoHS Compliant

o Fully Assembled and Tested
