Analog Devices Inc./Maxim Integrated MAXM17623EVKITE#

Overview

MAXM17623EVKITE# from Analog Devices is an evaluation kit designed to validate the performance of the MAXM17623 and MAXM17624 uSLIC™ power modules. It supports 1.5V/1A (MAXM17623) and 3.3V/1A (MAXM17624) output configurations, operates from 2.9V–5.5V input, features selectable PWM/PFM mode, and delivers up to 95.2% efficiency at 5V_IN/3.3V_OUT. It is used for rapid prototyping of compact, high-efficiency DC-DC conversion in space-constrained industrial and embedded systems.

For engineers reviewing the MAXM17623EVKITE# datasheet, MAXM17623EVKITE# pinout, MAXM17623EVKITE# application, or MAXM17623EVKITE# equivalent, this kit provides a fully assembled, tested, CISPR32 Class B-compliant platform to characterize transient response, efficiency, EMI, thermal behavior, and startup/shutdown sequencing of both MAXM17623 and MAXM17624 modules under real-world load and input conditions.

Technical Context

The MAXM17623EVKITE# integrates two electrically isolated evaluation circuits on a single PCB-one for the MAXM17623 (2MHz switching, 1.5V fixed output) and one for the MAXM17624 (4MHz switching, 3.3V fixed output). Each circuit includes dedicated input/output pads, jumper-selectable EN/UVLO and MODE/SYNC control, PGOOD monitoring, and optimized component selection (e.g., 22μF/6.3V C108 for MAXM17623; 10μF/16V C208 for MAXM17624).

EMI compliance is achieved via integrated input filtering (L101/C102/C103 for MAXM17623; L201/C202/C203 for MAXM17624), low-inductance layout, and optional hot-plug damping capacitors (C104/C204, 47μF/8V tantalum). Measured radiated and conducted emissions meet CISPR32 Class B limits per test reports shown in the documentation.

FAQ

What is the primary function of the MAXM17623EVKITE#?

The MAXM17623EVKITE# is a dual-channel evaluation kit that enables hardware engineers to independently assess the electrical performance, thermal behavior, and EMI characteristics of both the MAXM17623 and MAXM17624 uSLIC™ power modules. It provides pre-configured 1.5V and 3.3V output sections with full test points, jumper-selectable operation modes, and documented CISPR32 Class B compliance - all on a single, ready-to-use PCB. The MAXM17623EVKITE# eliminates the need for custom prototyping when validating these modules in space-constrained applications.

Does the MAXM17623EVKITE# support adjustable output voltages?

Yes - while the MAXM17623EVKITE# is preset to 1.5V for the MAXM17623 section and 3.3V for the MAXM17624 section, both outputs are adjustable via external resistor dividers. For the MAXM17623, R102 (33.2kΩ) and R103 (37.4kΩ) set the feedback node; for the MAXM17624, R202 (118kΩ) and R203 (37.4kΩ) perform the same function. The MAXM17623EVKITE# schematic and bill of materials confirm these components are populated and accessible for reconfiguration per the MAXM17623/MAXM17624 data sheet's adjusting output voltage procedure.

How does the MAXM17623EVKITE# achieve CISPR32 Class B compliance?

The MAXM17623EVKITE# achieves CISPR32 Class B compliance through a combination of integrated EMI filtering (L101/C102/C103 for MAXM17623; L201/C202/C203 for MAXM17624), optimized PCB stack-up and layout (including ground plane integrity and minimized high-di/dt loop areas), and strategic placement of damping capacitors (C104/C204). Radiated and conducted emission test results (toc25–toc28) explicitly state "MEASURED ON MAXM17623EVKITE#" and "MEASURED ON MAXM17624EVKITE#", confirming compliance was validated on this exact board revision using the specified component values and layout.

Can the MAXM17623EVKITE# evaluate both modules simultaneously?

No - although the MAXM17623EVKITE# hosts both the MAXM17623 and MAXM17624 modules on the same PCB, their input and output sections are electrically isolated. Engineers must power and load each section independently: the MAXM17623 side requires 2.9V–5.5V input and a 1.5V-compatible load; the MAXM17624 side requires 3.6V–5.5V input and a 3.3V-compatible load. This isolation prevents cross-talk and allows accurate, independent characterization of each module's efficiency, transient response, and stability - as demonstrated in the separate performance plots (toc01–toc18) labeled for each device.

What jumpers control enable and mode selection on the MAXM17623EVKITE#?

The MAXM17623EVKITE# uses four dedicated jumpers: JU101 and JU102 for the MAXM17623 section; JU201 and JU202 for the MAXM17624 section. JU101/JU201 configure EN/UVLO (shunt position 1–2 = enabled; 2–3 = disabled). JU102/JU202 configure operation mode (shunt position 1–2 = PWM; open = PFM). Table 1 and Table 2 in the documentation specify these mappings, and the board silkscreen labels each jumper location. These physical jumpers allow deterministic, repeatable configuration without soldering or firmware changes - critical for consistent lab validation of the MAXM17623EVKITE#.
