Analog Devices Inc./Maxim Integrated MAX20310EVKIT#

Overview

MAX20310EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit for the MAX20310 medical wearable power-management IC, featuring a single-inductor multiple-output (SIMO) buck-boost regulator, two LDOs, voltage monitor multiplexer, and I²C interface - all operating from 0.8V to 2.0V battery input for ultra-low-power clinical monitoring devices.

For engineers reviewing the MAX20310EVKIT# datasheet, MAX20310EVKIT# pinout, MAX20310EVKIT# application, or MAX20310EVKIT# equivalent, this board enables rapid validation of SIMO rail sequencing, I²C register configuration, negative-supply power architecture, and inductor selection across seven discrete values (1.0µH–6.8µH) in medical-grade wearable energy management systems.

Technical Context

The MAX20310EVKIT# implements the full functional interface of the MAX20310 IC, including its unique negative-supply topology where BATN serves as the battery negative terminal and GND acts as system ground - requiring strict polarity verification before power-up. All 16 bumps of the WLP package are broken out to test points or connectors J1/J2.

Hardware supports complete I²C-based configuration of output voltages, enable states, fault reporting, and button-monitoring behavior. The kit includes one pre-installed Murata DFE201610E-1R5M=P2 (1.5µH) inductor and six alternate inductors (1.0µH–6.8µH) for evaluating efficiency, transient response, and size trade-offs under varying load conditions.

FAQ

What is the primary function of the MAX20310EVKIT#?

The MAX20310EVKIT# is an evaluation platform for the MAX20310 IC, enabling engineers to validate its SIMO buck-boost regulator, dual LDOs, voltage monitor, button monitor, and I²C programmability in ultra-low-voltage medical wearable applications. It provides full access to all 16 bumps and supports rapid configuration and measurement without custom PCB design.

Does the MAX20310EVKIT# require a special power connection method?

Yes - the MAX20310EVKIT# uses a negative-supply architecture: the battery's negative terminal connects to BATN, and the positive terminal connects to GND. This is critical for correct operation. The board lacks reverse-battery protection, so polarity must be verified before applying power to avoid damage to the MAX20310EVKIT# or connected equipment.

Which inductors are included with the MAX20310EVKIT#?

The MAX20310EVKIT# ships with one installed Murata DFE201610E-1R5M=P2 (1.5µH) inductor and six additional inductors: 1.0µH (Bourns SRP2010-1R0M), 2.2µH, 3.3µH, two 4.7µH variants, and 6.8µH (all Murata). These allow systematic evaluation of inductor value impact on efficiency, ripple, and thermal performance.

How are the MAX20310EVKIT# connectors J1 and J2 used?

J1 (10-pin) carries digital control and monitoring signals: SDA, SCL, KIN, KOUT, RST#, MPC, MPO, MON, and GND. J2 (9-pin) breaks out power rails: B1OUT, B2OUT, L1OUT, L2OUT, CAP, LX, BATN, and GND. Both headers support standard 0.1" pitch probes or ribbon cables for interfacing with host controllers or test equipment.

Can the MAX20310EVKIT# be used to evaluate I²C register programming?

Yes - the MAX20310EVKIT# supports full I²C register access to configure output voltages, enable/disable states, fault thresholds, and key-monitoring behavior. SDA (J1 pin 4) and SCL (J1 pin 6) are directly accessible, and the board includes pull-up resistors compatible with standard I²C master devices operating at 100kHz or 400kHz.
