MAX17014 Evaluation Kit

General Description

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 pan-

els. 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 sin-

gle-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 +10.8V

to +13.2V, as configured. The step-down switching reg-

ulator 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 sur-
