MAX38904B TDFN Evaluation Kit

General Description

Quick Start

The MAX38904B TDFN evaluation kit (EV kit) evaluates

the MAX38904B in a TDFN package. The MAX38904B

is a low noise linear regulator. The EV kit operates over

an input range of 1.7V to 5.5V and provides a resistor

conﬁgurable output voltage range from 0.6V to 5.0V. The

EV kit can deliver up to 2A of current.

Required Equipment

● MAX38904B TDFN EV kit

● 5.5V, 5A DC power supply

● Electronic load capable of 2A

● Digital voltmeter (DVM)

Features

● Evaluates the MAX38904B IC in a 10-pin

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.

(3mm x 3mm) TDFN

● 1.7V to 5.5V Input Range

1) Verify that jumper JU101 is shunted on pins 1 and 2

● 0.6V to 5.0V Resistor Configurable Output Voltage

(Default Output Set to 3.3V)

(EV kit enabled).

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

● Up to 2A Output Current

nearest GND terminal posts.

● Proven 2-Layer 1-oz Copper PCB Layout

● Demonstrates Compact Solution Size

● Fully Assembled and Tested

3) Connect the 2A electronic load between the OUT and

nearest GND terminal posts.

4) Connect the DVM between the OUT and nearest

GND terminal posts.
