MAX17014EVKIT+: 4Ch LCD Supply, 10.8 ~ 13.2V in

Summary

The MAX17014 evaluation kit (EV kit) is a fully assembled and tested surface-mount printed-circuit board (PCB) that provides the voltages and features required for thin film transistor (TFT) liquid-crystal display (LCD) TV panels.

The EV kit includes a step-down switching regulator, a step-up switching regulator, a positive two-stage charge pump for the TFT gate-on supply, a negative single-stage charge pump for the TFT gate-off supply, and two high-current operational amplifiers (op amps).

The EV kit operates from a DC supply voltage of +10.8 V to +13.2 V, as configured. The step-down switching regulator is configured for a +3.3V output providing at least 2A. The step-up switching regulator is configured for a +16V output providing at least 1.5A. The positive charge pump is configured for a +35V output providing at least 50mA. The negative charge pump is configured for a -6V output providing at least 100mA. High frequency operation (1.2MHz) allows the use of tiny surface mount components to minimize the thickness of LCD panel designs.

The EV kit features two high-performance operational amplifiers (op amps) designed to drive the LCD backplane (VCOM). Power to the VCOM amplifiers comes from the step-up switching regulator output.
