Analog Devices Inc./Maxim Integrated MAXM17630EVKIT#

Overview

MAXM17630EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to validate the MAXM17630, MAXM17631, and MAXM17632 uSLIC™ step-down power modules. It supports three independent test configurations: 3.3V/1A (900kHz), 5V/1A (1250kHz), and 12V/1A (2150kHz), each with programmable EN/UVLO, PWM/PFM/DCM mode selection, external clock synchronization, and CISPR-22 Class B EMI compliance.

For engineers reviewing the MAXM17630EVKIT# datasheet, MAXM17630EVKIT# pinout, MAXM17630EVKIT# application, or MAXM17630EVKIT# equivalent, this kit enables rapid characterization of input voltage range (4.5–36V), efficiency (up to 93.12% at 24V→12V), transient response, output ripple, and stability margins across all three module variants in real-world PCB layout conditions.

Technical Context

The MAXM17630EVKIT# hosts three electrically isolated evaluation circuits on a single PCB-each configured for one uSLIC™ module (MAXM17630, MAXM17631, MAXM17632). Each circuit includes resistor-programmable switching frequency (via RT pin), adjustable UVLO threshold (via RUPPER/RLOWER divider), and jumper-selectable operation modes (PFM/DCM/PWM) and SYNC source routing.

It integrates proven EMI filtering (input EMI pads, ceramic + electrolytic input caps), optimized thermal layout with exposed pad grounding, and full-spectrum performance validation-including Bode plots (phase margin ≥68°), radiated/conducted emissions below CISPR-22 Class B limits, and load transient response under 10mA–1A steps.

FAQ

What does the MAXM17630EVKIT# evaluate?

The MAXM17630EVKIT# evaluates three distinct Maxim uSLIC™ power modules: MAXM17630 (3.3V fixed output), MAXM17631 (5V fixed output), and MAXM17632 (adjustable 0.9V–12V output). Each is implemented as an independent, electrically isolated circuit on the same PCB, allowing concurrent or sequential testing of input range, efficiency, transient response, and EMI behavior without hardware modification. The MAXM17630EVKIT# itself is not a functional power supply but a reference design and measurement platform for these modules.

Can the MAXM17630EVKIT# be used to evaluate only the MAXM17630 module?

Yes. The MAXM17630EVKIT# allows standalone evaluation of the MAXM17630 module by powering only its VIN_EMI1 and PGND1 pads, configuring JU101/JU102 per Table 1 and Table 2, and monitoring VOUT1. The other two channels (MAXM17631/MAXM17632) remain inactive unless powered and enabled. This isolation ensures accurate characterization of the MAXM17630 under its specified 4.5–36V input range and 900kHz switching frequency without cross-coupling effects.

Does the MAXM17630EVKIT# support external clock synchronization?

Yes. Each channel of the MAXM17630EVKIT# provides a MODE/SYNC pin (JU102, JU202, JU302 unconnected by default) that accepts an external clock signal between 1.1×fSW and 1.4×fSW - i.e., 990–1260kHz for MAXM17630, 1375–1750kHz for MAXM17631, and 2365–3010kHz for MAXM17632. The kit includes series resistors and routing to support clean injection, and oscilloscope waveforms (toc46–toc47) confirm reliable synchronization with minimal jitter and no loss of regulation during full-load operation.

What EMI performance does the MAXM17630EVKIT# demonstrate?

The MAXM17630EVKIT# meets CISPR-22 Class B conducted and radiated emissions limits across all three modules, as verified in Figures toc54–toc56. This compliance is achieved through integrated EMI filter components (C101–C103, C201–C203, C301–C303), optimized PCB layer stack-up (4-layer board with dedicated ground planes), and careful placement of high-dI/dt nodes. Radiated emissions are measured in both horizontal and vertical scans, confirming robustness for industrial environments where EMI immunity and regulatory certification are critical.

How is output voltage adjusted on the MAXM17632 channel of the MAXM17630EVKIT#?

The MAXM17632 channel on the MAXM17630EVKIT# is preset to 12V using R305 = 634kΩ and R306 = 51kΩ in the feedback divider. To adjust output voltage within the 0.9V–12V range, replace these resistors per the formula VOUT = 0.9V × (1 + R305/R306) and Table 2 in the MAXM17630/MAXM17631/MAXM17632 data sheet. The kit's schematic (page 17) shows the FB node connection, and the bill of materials confirms 0402 footprint compatibility for field reconfiguration.
