MAX20003 Evaluation Kit

General Description

The MAX20003 evaluation kit (EV kit) demonstrates the

MAX20002/MAX20003 high-voltage, current-mode step-

down converters with low operating current. The EV kit

operates over a wide 3.5V to 36V input range and the

output is set for 5V at 3A.

The EV kit comes with the MAX20003ATPA/V+ installed.

Features and Benefits

● Wide 3.5V to 36V Input Supply Range

● Forced-PWM or Skip-Mode Operation

● Programmable Switching Frequency

● Power-Good Output

● Proven PCB Layout

● Fully Assembled and Tested

19-7413; Rev 0; 5/14

Ordering Information appears at end of data sheet.

Quick Start

Required Equipment

● MAX20003EVkit

● 14V,2ADCpowersupply

● Electronicloadcapableof3A

● Digitalvoltmeter(DVM)

Procedure

The EV kit is fully assembled and tested. Follow the steps

below to verify board operation.

Caution: Do not turn on

supplies until all connections are made.

1) VerifythatjumpersJU1–JU4areintheirdefaultposi-

tions,asshowninTables1–4.

2) ConnectthepowersupplybetweentheSUPSWand

4) Connect the DVM between the OUT and nearest

PGNDtestpoints.

5) Turn on the power supply.

6) Enable the electronic load.

7) VerifythatthevoltageattheOUTtestpointisapproxi-
