General Description

The MAX17062 evaluation kit (EV kit) is a fully assem-

bled and tested surface-mount PCB that provides the

voltages required for active-matrix, thin-film transistor

(TFT), liquid-crystal displays (LCDs). The EV kit con-

tains a pulse-width-modulated (PWM) step-up switch-

ing regulator, a positive single-stage charge pump for

the TFT gate-on supply, and a negative single-stage

charge pump for the TFT gate-off supply.

The EV kit operates from a DC supply voltage of +4.5V

to +5.5V and is configured to operate with a switching

frequency of 1.2MHz. The step-up switching regulator

is configured for a +15V output and can provide 600mA

with a +4.5V input. The positive charge pump is config-

ured for a +29V output providing 30mA. The negative

charge pump is configured for a -15V output providing

30mA.

The MAX17062 EV kit features low-quiescent current

and high-conversion efficiency (90%). The high switch-

ing frequency allows the use of small, surface-mount

components.
