MAX20310 EV kit
for low-power medical applications. The device includes
a voltage monitor multiplexer, a button monitor, a single-
inductor, multiple-output (SIMO) buck-boost regulator,
and two low-dropout (LDO) linear regulators.
Power supply capable of supplying +0.8V to +2.0V
Digital multimeter (DMM)

I C master device
Refer to the MAX20310 IC data sheet for detailed information
regarding the operation and features of the devices.
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
Features
● RoHS Compliant
● Proven PCB Layout
● Fully Assembled and Tested
1) Connect the positive terminal of the power supply to
GND and the common terminal to BATN (Note 1).
2) Pull the KIN pin to BATN until the device wakes up
(400ms (typ)).
2
● I C Serial Interface
3) Use the DMM to measure the voltage at B1OUT and
verify that it is 1.8V.
● Multiple Inductor Options Included

4) Use the I C master to configure the MAX20310 as
desired.
Ordering Information appears at end of data sheet.
Detailed Description of Hardware
The MAX20310 evaluation kit (EV kit) evaluates the
MAX20310 medical wearable, power-management solution.
The device is optimized for low-voltage applications and
operates on battery voltages from 0.8V to 2.0V. The EV kit
breaks out all device bumps for ease of measurement.
Negative Supply
The MAX20310 requires a negative power supply
configuration. Therefore, the positive terminal of a battery or
power supply connects to GND and the negative terminal
connects to BATN. There is no reverse-battery protection
on the MAX20310 EV kit, so users are strongly advised
to verify power connections before connecting a battery or
turning on a supply.
Note 1: MAX20310 is powered by a negative supply. See
