The MAX17075EVKIT+ from Maxim Integrated Products is a MAX17075 evaluation kit. It features required for active matrix thin-film transistor, liquid-crystal display 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. It 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.
