General Description

The MAX17112 evaluation kit (EV kit) provides a proven

design to evaluate the MAX17112 high-performance

step-up DC-DC converter, which provides a regulated

supply voltage for active-matrix thin-film transistor (TFT)

liquid-crystal displays (LCDs).

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

5.5V and is configured to operate with a switching fre-

quency of 1MHz. The high switching frequency allows

the use of small, surface-mount components. The step-

up switching regulator is configured for a 15V output

and provides 600mA with a 4.5V input.

Features

o 4.5V to 5.5V Input Range

o 15V Output Voltage

o 1MHz Switching Frequency

o Programmable Soft-Start

o Lead(Pb)-Free and RoHS Compliant

o Proven PCB Layout

o Fully Assembled and Tested
