MAX20310 Evaluation Kit

General Description

Quick Start

The MAX20310 evaluation kit (EV kit) is a fully assembled

Required Equipment

Before beginning, the following equipment is needed:

and tested circuit for evaluating the MAX20310 medical

wearable, power-management solution with I C capability

●

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)).

● 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

MAX20310 Evaluation Kit

EV kit contains several inductors of different values and

from different suppliers. Table 1 provides the part numbers,

manufacturers, and values of the included inductors.

Inductors

All four of the MAX20310’s voltage rails are generated

by a single-inductor, multiple-output (SIMO) buck-boost

regulator. In order to provide maximum ﬂexibility in

evaluating the MAX20310 and selecting an inductor, this
