Analog Devices Inc./Maxim Integrated MAXM17543EVKIT#

Overview

MAXM17543EVKIT# from Maxim Integrated is an evaluation kit designed to demonstrate and validate the MAXM17543 Himalaya step-down power module - a 4.5V–42V input, 2.5A integrated DC-DC converter with internal inductor, dual MOSFETs, controller, and compensation. It supports adjustable output (0.9V–12V), PWM/PFM/DCM modes, and operates across –40°C to +125°C ambient.

For engineers reviewing the MAXM17543EVKIT# datasheet, MAXM17543EVKIT# pinout, MAXM17543EVKIT# application, or MAXM17543EVKIT# equivalent, this kit enables rapid prototyping of industrial point-of-load supplies, FPGA/DSP rails, and HVAC control power stages - with full thermal, efficiency, transient, and EMI characterization capability out of the box.

Technical Context

The MAXM17543EVKIT# implements the MAXM17543 power module in a fully assembled, tested PCB layout optimized for low noise, thermal performance, and CISPR-22 Class B compliance. It includes all five required external components (input/output capacitors, feedback resistors, soft-start capacitor) plus SYNC, MODE, RT, and EN configuration jumpers for real-time mode switching and frequency tuning.

It supports direct measurement of key system-level behaviors: load transient response (e.g., 0.05A→1.25A in 100µs), startup/shutdown sequencing (EN- or VIN-controlled), prebias start-up, short-circuit protection (hiccup mode), RESET assertion timing, and closed-loop stability (53.3° phase margin at 54.9kHz crossover).

FAQ

What is the primary purpose of the MAXM17543EVKIT#?

The MAXM17543EVKIT# is a fully assembled evaluation board for the MAXM17543 power module. It enables engineers to verify electrical performance - including efficiency, transient response, thermal behavior, and EMI - under real-world operating conditions before committing to custom PCB design. The board includes all necessary passive components and configurable jumpers for immediate bench testing of the MAXM17543.

Does the MAXM17543EVKIT# support adjustable output voltage and frequency?

Yes. The MAXM17543EVKIT# supports output voltages from 0.9V to 12V using the onboard FB resistor divider network, and switching frequencies from 100kHz to 1.8MHz via the RT resistor footprint or external SYNC signal. Default configuration delivers 5V at 500kHz (RT open), but all variants listed in Table 1 of the MAXM17543 datasheet are reproducible on this kit with minor component changes.

Can the MAXM17543EVKIT# be used to evaluate light-load efficiency modes?

Yes. The MAXM17543EVKIT# allows direct comparison of PWM, PFM, and DCM operation via the MODE pin jumper. Efficiency curves for PFM and PWM modes across multiple VOUT settings (e.g., 3.3V, 5V, 12V) and load currents (0.05A–2.5A) are provided in the MAXM17543 datasheet, all measured using the MAXM17543EVKIT# - confirming sub-100µA quiescent current in PFM mode at light loads.

How does the MAXM17543EVKIT# support thermal validation?

The MAXM17543EVKIT# implements the exact thermal pad layout specified for the MAXM17543 SiP: EP1 (SGND), EP2 (LX), and EP3 (OUT) connect to dedicated 1in × 1in copper islands with multiple thermal vias. This enables accurate junction-to-ambient thermal resistance measurement (θJA = 30.8°C/W on 4-layer board) and validates derating curves - such as 2.5A output at +125°C ambient with no forced airflow - per the datasheet's toc43 plot.

Is the MAXM17543EVKIT# compliant with EMC standards?

Yes. The MAXM17543EVKIT# meets CISPR-22 Class B conducted and radiated emissions when configured per the datasheet's EMI test setup: C4/C14 open, L1 shorted, C7=220pF, C17/C18=150pF. Radiated emission plots (toc45) and conducted noise data confirm compliance up to 1GHz, enabling pre-compliance validation for industrial end equipment without requiring additional filtering.
