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.

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.

MAX17220 Evaluation Kit
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 MAX17220 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.
Each circuit provides resistor-configurable output voltages
from 1.8V to 5V in 100mV/step.

JU101
The MAX17220 EV Kit comes with a MAX17220ELT+
(µDFN) and a MAX17220ENT+ (WLP) installed. The
MAX17220ELT+ circuit is configured for a 3V output, and
can deliver 100mA with 1.8V input. The MAX17220ENT+
circuit is configured for a 5V output, and can deliver
100mA with 3V input.

*Default position.
The WLP circuit on the EV kit provides a jumper (JU1) to
enable or disable the MAX17220ENT+. Refer to Table 1 for
JU1 jumper settings.
Evaluating other ICs
The MAX17220 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 package.
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 MAX17220ELT+. Refer to Table 2
for JU101 jumper settings.
Component Suppliers
Battery Holders
The MAX17220 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.
