Evaluates: MAX17220–MAX17225

MAX17220 Evaluation Kit

General Description

Quick Start

The MAX17220 evaluation kit (EV kit) evaluates the

MAX17220–MAX17225 IC family of ultra-low quiescent

current step-up DC-DC converters. The MAX17220 EV

kit features two independent circuits to evaluate two

diﬀerent IC packages of the MAX17220–MAX17225

family. Both circuits on the EV kit operate over an input

range of 400mV to 5.5V, depending on load, with 0.88V

typical startup with 3kΩ load. Each circuit provides

resistor-conﬁgurable output voltages from 1.8V to 5V in

100mV/step.

Required Equipment

●

MAX17220 EV kit

1.8V to 5V, 3A DC power supply

Electronic load capable of 100mA

Digital voltmeter (DVM)

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.

The EV kit comes with the MAX17220ELT+ and

MAX17220ENT+ installed.

Testing the 3V Output Circuit

Features

1) Verify that jumper JU101 is in its default position, as

shown in Table 2.

2) Connect the power supply between the IN and nearest

GND terminal posts.

● Two Independent Circuits on One Board

• Evaluates the MAX17220–MAX17225 IC Family in

a 6-pin µDFN

3) Connect the electronic load between the 3V output

and nearest GND terminal posts.

• Evaluates the MAX17220–MAX17225 IC Family in

a 6-pin Wafer-Level Package (WLP)

4) Connect the DVM between the 3V output and nearest

GND terminal posts.

5) Set the input power supply to 1.8V and turn on the

power supply.

● 400mV to 5.5V Input Range

● 1.8V to 5V Configurable Output Voltage in

100mV/step

6) Set the electronic load to 100mA and enable the

electronic load.

7) Verify that the voltage at the 3V terminal post is

approximately 3V.

● Up to 100mA/225mA/425mA Output Current

● Proven 2-Layer 1oz Copper PCB Layout

● Demonstrates Compact Solution Size

● Fully Assemble and Tested

Testing the 5V Output Circuit

1) Verify that jumper JU1 is in its default position, as

shown in Table 1.

2) Connect the power supply between the IN1 and

nearest GND1 terminal posts.

3) Connect the electronic load between the 5V output

and nearest GND1 terminal posts.

4) Connect the DVM between the 5V output and a

nearest GND1 terminal posts.
