Applications/Uses

Description

The MAX17075 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that provides 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 positive charge pump for the TFT gate-on supply, a single-stage negative charge pump for the TFT gate-off supply, and a high-current op amp. Also included is a logic-controlled high-voltage switch array, with capacitor control delay, for the positive gate-driver supply. A capacitive 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%) nominal input voltage, the step-up switching regulator provides 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.
