Analog Devices Inc./Maxim Integrated MAXM17626EVKIT#

Overview

MAXM17626EVKIT# from Maxim Integrated is an evaluation kit designed to validate the MAXM17626 10-pin u-SLIC power module in real application circuits. It delivers a fixed 3.3V output at up to 600mA load, operates from 3.6V–5.5V input, and features a 4MHz switching frequency, selectable PWM/PFM mode, and integrated PGOOD signal. The kit supports rapid prototyping of compact, high-efficiency point-of-load supplies for space-constrained industrial and embedded systems.

For engineers reviewing the MAXM17626EVKIT# datasheet, MAXM17626EVKIT# setup, MAXM17626EVKIT# test procedure, or MAXM17626EVKIT# component bill of materials, this page provides verified configuration guidance, jumper settings (JU201/JU202), efficiency data (94.5% at 5V_IN/3.3V_OUT/400mA), PCB layout references, and validated external component values-including C204 (10μF/10V X7R) and R202/R203 (118kΩ/37.4kΩ) for output voltage programming.

Technical Context

The MAXM17626EVKIT# hosts a fully assembled and tested MAXM17626AMB+ module configured for 3.3V output with 4MHz fixed-frequency operation. It implements dual-mode control via JU202 jumper (PWM default open = PFM at light load), includes internal 1ms soft-start, and provides a PGOOD output pulled up to VIN with dedicated PGND reference.

Input conditioning uses C203 (2.2μF/10V X7R) and optional C202 (47μF/8V tantalum) for hot-plug and long-cable damping; output filtering uses C204 (10μF/10V X7R) and low-ESR ceramic layout optimized per Maxim's proven PCB design. All components are surface-mount, 0402–0805 footprint, with electrically isolated MAXM17625/MAXM17626 sections on a single board.

FAQ

What is the primary function of the MAXM17626EVKIT#?

The MAXM17626EVKIT# is a fully assembled evaluation platform for the MAXM17626 power module. It enables engineers to verify electrical performance-including regulation accuracy, efficiency, transient response, and PGOOD timing-under real-world conditions. The kit includes all necessary passive components, jumpers for mode selection (PWM/PFM), and clearly labeled test points, eliminating prototype PCB development time for the MAXM17626AMB+ module.

How do I configure the MAXM17626EVKIT# for PWM mode operation?

To configure the MAXM17626EVKIT# for PWM mode, install a shunt on jumper JU202 pins 1–2 (connecting MODE to GND). This forces continuous PWM operation across all load conditions. By default, JU202 is open (PFM mode at light load), as specified in Table 2 of the MAXM17626EVKIT# documentation. Confirm operation using the PGOOD signal and output ripple measurement with a DMM or oscilloscope.

What input and output capacitors are used on the MAXM17626EVKIT#?

The MAXM17626EVKIT# uses C203 (2.2μF/10V X7R ceramic) as the main input capacitor and C204 (10μF/10V X7R ceramic) as the output capacitor. Optional damping capacitors include C202 (47μF/8V tantalum) for long-cable/hot-plug suppression and C201/C206 (0.1μF/10V X7R) for high-frequency noise attenuation. All values are validated per Maxim's application guidelines for the MAXM17626 module.

Can the MAXM17626EVKIT# be used to evaluate adjustable output voltages?

Yes-the MAXM17626EVKIT# supports output adjustment from 1.5V to 3.3V using the R202/R203 resistor divider network. While factory-configured for 3.3V, replacing R202 (118kΩ) and/or R203 (37.4kΩ) per the MAXM17626 data sheet allows precise tuning. The EV kit's silkscreen and schematic (page 10) identify these components and their connections to the FB pin of the MAXM17626AMB+ module.

Does the MAXM17626EVKIT# include both MAXM17625 and MAXM17626 circuits on one board?

Yes-the MAXM17626EVKIT# shares a single PCB with the MAXM17625EVKIT# design, hosting two electrically isolated evaluation sections. The MAXM17626 section (U201, C201–C206, R201–R203, JU201/JU202) is fully independent and can be powered and tested separately from the MAXM17625 section. Each has dedicated VIN, VOUT, GND, and jumper locations, enabling concurrent or comparative evaluation of both modules.
