The MAX17075 evaluation kit (EV kit) is a fully assem-

bled and tested surface-mount circuit board that pro-

vides the voltages and features required for active-

matrix thin-film transistor (TFT), liquid-crystal display

(LCD) panels in LCD monitors and LCD TVs. The EV kit

contains a step-up switching regulator, a two-stage pos-

itive charge pump for the TFT gate-on supply, a single-

stage negative charge pump for the TFT gate-off sup-

ply, and a high-current op amp. Also included is a logic-

controlled high-voltage switch array, with capacitor con-

trol delay, for the positive gate-driver supply. A capaci-

tive dummy load is provided at the high-voltage switch

output for ease of testing without an attached panel.

The MAX17075 EV kit is designed to operate from a DC

supply voltage of +2.5V to +5.5V. At +5V (±10%) nomi-

nal input voltage, the step-up switching regulator pro-

vides a +13V output and up to 500mA. The positive

charge pump provides a +30V output and up to 30mA.

The negative charge pump provides a -7V output and

up to 60mA. The high-current op amp provides a +6.5V

output that can source or sink 500mA peak current. The

high-voltage switch array is controlled by external logic.

The MAX17075 switches at 1.2MHz, allowing the use of

tiny surface-mount components. The MAX17075 thin

QFN package (0.8mm maximum height) with low-profile

external components allows this circuit to be less than

3mm high.
