Analog Devices Inc./Maxim Integrated MAXM17544EVKIT#

Overview

MAXM17544EVKIT# from Maxim Integrated is an evaluation kit designed to demonstrate and validate the MAXM17544 Himalaya step-down power module - a 4.5V–42V input, 0.9V–12V adjustable output, 3.5A integrated SiP DC-DC converter with internal MOSFETs, inductor, and compensation. It enables rapid prototyping of industrial point-of-load supplies for FPGA, DSP, and base station applications.

For engineers reviewing the MAXM17544EVKIT# datasheet, MAXM17544EVKIT# pinout, MAXM17544EVKIT# application, or MAXM17544EVKIT# equivalent, this kit provides verified thermal performance, CISPR-22 Class B emissions compliance, startup/enable/shutdown waveforms, load transient response (≤200mV deviation at 1.75A step), and full configuration flexibility via RT, MODE, SS, and SYNC pins.

Technical Context

The MAXM17544EVKIT# implements the MAXM17544 power module in a fixed-layout, pre-tested PCB configuration with optimized component selection per Table 1 of the datasheet - including 2×2.2µF/100V input ceramics, 1×22µF/10V output ceramic, and proper layout for LX/OUT/PGND thermal islands. It supports all three control modes (PWM, PFM, DCM) and external frequency synchronization from 100kHz to 1.8MHz.

Test data captured using this kit validates key system-level behaviors: ≤1024-cycle RESET assertion delay after FB drops below 92% regulation, hiccup-mode overload protection triggered at VFB ≤ 0.58V, and thermal shutdown at +165°C with 10°C hysteresis - all under real-world ambient conditions up to +125°C.

FAQ

What is the primary function of the MAXM17544EVKIT#?

The MAXM17544EVKIT# is an evaluation kit that demonstrates the MAXM17544 Himalaya step-down power module in a fully assembled, tested PCB layout. It enables engineers to validate input/output voltage ranges, efficiency curves, thermal behavior, transient response, and EMI performance without designing a custom board - directly supporting early-stage power architecture decisions for industrial and telecom systems.

Does the MAXM17544EVKIT# support all operating modes of the MAXM17544?

Yes, the MAXM17544EVKIT# supports PWM, PFM, and DCM operation via jumper-selectable MODE pin configuration (SGND, open, or VCC). Each mode has been characterized on the kit - including efficiency vs. load plots (toc01–toc12), startup timing (toc29–toc31), and load transients (toc23–toc28) - confirming full functional coverage per the MAXM17544 datasheet.

Can the MAXM17544EVKIT# be used to verify CISPR-22 Class B compliance?

Yes - the MAXM17544EVKIT# was used to generate the radiated emissions plot (toc45) referenced in the MAXM17544 datasheet. Test conditions are documented: VIN = 24V, VOUT = 5V, IOUT = 3.5A, C4/C14 open, L1 shorted, C7 = 220pF, C17/C18 = 150pF. This makes MAXM17544EVKIT# a validated starting point for system-level EMC pre-compliance checks.

What external components are pre-installed on the MAXM17544EVKIT#?

The MAXM17544EVKIT# includes all critical external components specified in Table 1 of the MAXM17544 datasheet: input capacitors (2×2.2µF/100V ceramics), output capacitor (1×22µF/10V ceramic for 5V operation), feedback resistors (RU/RB), soft-start capacitor (CSS), RT resistor (26.7kΩ for 740kHz), and SYNC termination. No additional parts are required to operate the MAXM17544EVKIT# out-of-box.

Is thermal performance data for the MAXM17544EVKIT# publicly available?

Yes - Figure toc43 ("Output Current vs. Ambient Temperature") in the MAXM17544 datasheet presents derating curves measured directly on the MAXM17544EVKIT# under no-airflow conditions. It shows maximum sustainable output current versus ambient temperature for VOUT = 3.3V, 5V, and 12V - enabling accurate thermal margining for end-equipment designs.
