MAX38903 TDFN Evaluation Kit

General Description

Quick Start

The MAX38903 TDFN evaluation kit (EV kit) evaluates

the MAX38903A/MAX38903B IC family of low noise linear

regulators. The EV kit operates over an input range of

1.7V to 5.5V and provides any output voltage range from

0.6V to 5.3V, and delivers up to 1A of current. The EV kit

comes with the MAX38903BATB+ installed.

Required Equipment

●

5.5V, 1A DC power supply

Electronic load capable of 1A

Digital voltmeter (DVM)

Features

Procedure

● Evaluates the MAX38903A/MAX38903B IC in a

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

below to verify board operation.

10-pin (3mm x 3mm) TDFN

● 1.7V to 5.5V Input Range

Caution:Donotturnonpowersupplyuntilallconnections

are completed.

● 0.6V to 5.3V Resistor Configurable Output Voltage

(MAX38903B, On Board with Output Set to 3.3V)

1) Verify that jumpers JU101, SELA and SELB are in

their default positions, as shown in Tables 1, 2, and 3.

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

nearest GND terminal posts.

3) Connect the 1A 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.

● 1.2V to 5.0V Jumper Configurable Output Voltage

(MAX38903A, with IC Replacement)

● Up to 1A Output Current

● Proven 2-Layer 1 oz Copper PCB Layout

● Demonstrates Compact Solution Size

● Fully Assembled and Tested

6) Enable the electronic load.

7) Verify that the voltage at the OUT terminal post is

approximately 3.3V.
