MAX17222 Evaluation Kit

General Description

Quick Start

The MAX17222 evaluation kit (EV kit) evaluates the

MAX17220–MAX17225 IC family of ultra-low quiescent

current step-up DC-DC converters. The MAX17222 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

●

MAX17222 EV kit

1.8V to 5V, 3A DC power supply

Electronic load capable of 225mA

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 MAX17222ELT+ and

MAX17222ENT+ 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 225mA 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.

MAX17222 EV Kit Files

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.

Spare Resistors and Inductors

Detailed Description of Hardware

The EV kit provides spare resistors and inductors on the

PCB’s bottom side. The spare resistors can be used to

reconﬁgure the EV kit to a diﬀerent output voltage (2V,

2.5V, 3V, or 3.3V). The spare inductors can be used to

reconﬁgure the EV Kit output current ratings.

The MAX17222 EV kit evaluates the MAX17220–

MAX17225 IC family of ultra-low quiescent current step-

up DC-DC converters. The MAX17222 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.

Each circuit provides resistor-conﬁgurable output voltages

from 1.8V to 5V in 100mV/step.

DESCRIPTION

The MAX17222 EV Kit comes with a MAX17222ELT+

(µDFN) and a MAX17222ENT+ (WLP) installed. The

MAX17222ELT+ circuit is conﬁgured for a 3V output, and

can deliver 225mA with 1.8V input. The MAX17222ENT+

circuit is conﬁgured for a 5V output, and can deliver

225mA with 3V input.

*Default position.

The WLP circuit on the EV kit provides a jumper (JU1) to

enable or disable the MAX17222ENT+. Refer to Table 1 for

JU1 jumper settings.

Evaluating Other ICs

The MAX17222 EV kit can also evaluate other ICs in the

MAX17220–MAX17225 IC family. To evaluate the other

ICs, replace U1 and/or U101 with the desired IC/IC pack-

age. Refer to the MAX17220–MAX17225 IC data sheet

for additional information.

EN for the µDFN Circuit

The µDFN circuit on the EV kit provides a jumper (JU101)

to enable/disable the MAX17222ELT+. Refer to Table 2

for JU101 jumper settings.

Battery Holders

Component Suppliers

The MAX17222 EV kit provides battery holders for each

of the two circuits. The battery holder V1 can accommodate

a CR1632 Lithium Coin cell to power the WLP circuit,

while the V101 can hold an Energizer 364/363 silver oxide

cell to power the µDFN circuit.
