MAXM38643A EMGA

Evaluation Kit

Evaluates: MAXM38643

General Description

Quick Start

Required Equipment

The MAXM38643A EMGA evaluation kit (EV kit) evaluates

the MAXM38643A IC in an EMGA package. The

MAXM38643A is an ultra-low quiescent current step-down

DC-DC converter. The EV kit operates over an input range

of 1.8V to 5.5V and provides resistor-configurable output

voltages from 0.7V to 3.3V. The EV kit delivers up to

600mA of current. The EV kit comes with the

MAXM38643AEMB+ installed.

Procedure

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

below to verify board operation.

Caution: Do not turn on power supply until all

connections are completed.

Features and Benefits

1. Verify that jumpers JU1 and JU2 are in their default

positions, as shown in Tables 1 and 2.

2. Connect the 5.5V power supply between the IN and

nearest GND terminal posts.

3. Connect the 600mA electronic load between the OUT

and nearest GND terminal posts.

4. Connect the DVM between the OUT and nearest GND

terminal posts.

5. Turn on the power supply.

6. Enable the electronic load.
