Analog Devices Inc./Maxim Integrated MAXM17905EVKIT#

Overview

MAXM17905EVKIT# from Maxim Integrated is an evaluation kit for the MAXM17905 fixed 5V, 300mA synchronous step-down uSLIC™ power module. It enables rapid validation of the Himalaya module's performance in industrial sensors, 4–20mA loop-powered systems, and USB Type-C loads-supporting input voltages from 4.5V to 24V, ±1.5% output regulation accuracy, and integrated soft-start (3.75ms).

For engineers reviewing the MAXM17905EVKIT# datasheet, MAXM17905EVKIT# pinout, MAXM17905EVKIT# application, or MAXM17905EVKIT# equivalent, this kit provides pre-layout PCB, test points for VIN/VOUT/EN/RESET, thermal performance characterization, and full support for evaluating PFM/PWM mode switching, hiccup overcurrent protection, and prebias startup behavior under real load transients.

Technical Context

The MAXM17905EVKIT# implements the MAXM17905 power module in a 2.6mm × 3mm × 1.5mm 10-pin uSLIC™ package with peak-current-mode control architecture. It includes all external passive components required for operation: input/output capacitors, feedback resistors (for adjustable variants), and layout-optimized ground plane routing per Maxim's reference design.

This kit supports functional verification of key system-level behaviors: open-drain RESET assertion at 92–95.5% FB threshold, EN/UVLO programmable threshold (1.06–1.28V), and thermal shutdown activation at 166°C with 10°C hysteresis-all while maintaining CISPR22 Class B conducted/radiated emissions compliance without added filtering.

FAQ

What is the primary function of the MAXM17905EVKIT#?

The MAXM17905EVKIT# is an evaluation kit designed exclusively for the MAXM17905 fixed 5V, 300mA uSLIC™ power module. It provides a ready-to-use PCB with test points, thermal vias, and optimized layout to validate electrical performance, transient response, efficiency, and protection features - eliminating custom design effort for initial power stage testing.

Does the MAXM17905EVKIT# support both PWM and PFM modes?

Yes, the MAXM17905EVKIT# supports both modes via the MODE pin on the MAXM17905 device. Pulling MODE to GND forces fixed-frequency PWM operation across all loads; leaving it unconnected enables automatic PFM mode at light loads. The kit includes jumpers and test points to configure and monitor mode selection in real time.

Can the MAXM17905EVKIT# be used to evaluate other Himalaya modules like MAXM17904 or MAXM17906?

No - the MAXM17905EVKIT# is specifically laid out for the MAXM17905 (fixed 5V output). While the pinout matches the MAXM17904/MAXM17906 family, the feedback network and output capacitor values are optimized for 5V regulation. Evaluation of MAXM17904 (3.3V) or MAXM17906 (adjustable) requires their respective kits: MAXM17904EVKIT# or MAXM17906EVKIT#.

What thermal performance data is provided with the MAXM17905EVKIT#?

The MAXM17905EVKIT# documentation includes ambient temperature vs. output current derating curves (up to 300mA at +125°C), thermal resistance (θJA = 41.56°C/W on four-layer board), and thermal shutdown behavior (trip at 166°C, 10°C hysteresis). IR images and junction temperature measurements under full load are included in the user guide.

Is EMI filtering integrated into the MAXM17905EVKIT# design?

Yes - the MAXM17905EVKIT# incorporates a certified CISPR22 Class B EMI filter: 82µH choke plus 0.1µF and 0.68µF capacitors. Radiated and conducted emission plots (measured per ANSI C63.4) are published in the datasheet, confirming compliance at full 300mA load with no additional external filtering required.
