MAX20343 Evaluation Kit

General Description

Quick Start

The MAX20343 evaluation kit (EV kit) is a fully assembled

andtestedcircuitthatevaluatestheMAX20343/MAX20344

3.5W, buck-boost regulator. The MAX20343 is designed

for low-noise, battery-powered applications that require

long runtimes. The EV kit is compatible with both the I C

controlled and single-pin-enabled versions of the

MAX20343/MAX20344.

Required Equipment

The following equipment is required to verify the function-

ality of this EV kit. The list assumes the EV kit is used with

the I C-controlled version of MAX20343.

● USB-A to Micro-USB Cable

● Host PC with One USB Port and the MAX20343

Evaluation Kit Tool Installed

Refer to the MAX20343/MAX20344 IC data sheet for

detailed information regarding the operation and features

of the device.

● Adjustable Power Supply with 5.5V Capability

● Voltmeter

Optional Equipment

Features

The following equipment can be used for more complete

evaluation of the EV kit:

● RoHS Compliant

● Proven PCB Layout

● Fully Assembled and Tested

● Two (2) Ammeters

● USB Controllable for I C Configured Devices

● Load (Electronic or Passive)

Procedure

Ordering Information appears at end of data sheet.

The EV kit is fully assembled and tested. Follow the

steps below to verify board operation when using the I C

controlled version of MAX20343:

3) Verify that the shunt jumpers are installed in their

default positions.

4) Set the voltage on the power supply to 3.3V, then

connect the positive terminal to V and the com-

mon/negative terminal to GND.

5) Verify that the GUI has detected and connected to the

EV kit and that LED D5 on the EV kit is illuminated.

6) On the General tab of the GUI, uncheck the boxes

for Output Voltage Interrupt Mask and Input UVLO

Interrupt Mask.

7) Press the Read button to read the interrupt states.

Verify that LED D2 is oﬀ.

8) Switch to the Buck-Boost tab of the GUI and verify

that the Output Voltage slider is set to 5.5V, then

enable the regulator using the Buck-Boost Enable

radio button.

9) Verify that LED D2 is illuminated.
