Analog Devices Inc./Maxim Integrated MAXM17904EVKIT#

Overview

MAXM17904EVKIT# from Maxim Integrated is an evaluation kit for the MAXM17904 Himalaya uSLIC step-down power module - a 3.3V fixed-output, 300mA DC-DC module in a 2.6mm × 3mm × 1.5mm uSLIC package operating from 4.5V to 24V input. It integrates controller, MOSFETs, compensation, and inductor, enabling plug-and-play power design for space-constrained industrial sensors and battery-powered equipment.

For engineers reviewing the MAXM17904EVKIT# datasheet, MAXM17904EVKIT# pinout, MAXM17904EVKIT# application, or MAXM17904EVKIT# equivalent, this kit provides validated reference layout, startup/soft-start characterization, load transient response measurement, and RESET signal timing verification - critical for rapid prototyping of point-of-load regulators in HVAC controls and 4–20mA sensor interfaces.

Technical Context

The MAXM17904EVKIT# supports evaluation of the MAXM17904 module's peak-current-mode control architecture, fixed 3.75ms soft-start, ±1.5% feedback accuracy, and hiccup-mode overcurrent protection. It enables validation of PFM/PWM mode switching via the MODE pin and open-drain RESET assertion at 92–95.5% FB threshold.

This kit implements the full recommended external circuitry: 1µF input capacitor (CIN), 10µF output capacitor (COUT), and proper ground plane routing per MAXM17904 EV kit layout guidelines. It facilitates measurement of efficiency (up to 92% at 12V_IN/3.3V_OUT), output ripple (<10mV_PP), and thermal performance across –40°C to +125°C ambient.

FAQ

What is the primary function of the MAXM17904EVKIT#?

The MAXM17904EVKIT# is an evaluation kit designed specifically to validate the electrical performance, thermal behavior, and system integration of the MAXM17904 3.3V/300mA uSLIC step-down power module. It provides a pre-layout PCB with optimized grounding, decoupling, and thermal vias - enabling engineers to measure efficiency, load transients, startup timing, and RESET signal behavior before committing to custom board design.

Does the MAXM17904EVKIT# support adjustable output voltage configurations?

No - the MAXM17904EVKIT# is configured exclusively for the MAXM17904 fixed 3.3V output module. It does not support the MAXM17906 adjustable variant. For adjustable output evaluation, the MAXM17906EVKIT# must be used, which includes resistor-divider networks (R1–R4) and FB loop compensation tailored for 0.9V–6.3V operation.

Can the MAXM17904EVKIT# be used to evaluate PFM vs. PWM mode switching?

Yes - the MAXM17904EVKIT# exposes the MODE pin, allowing direct connection to GND (for forced PWM) or leaving it unconnected (for automatic PFM at light loads). This enables measurement of quiescent current (95μA typical in PFM), efficiency curves across load range, and transient response differences between modes using onboard test points.

What safety and reliability features of the MAXM17904 are verified using the MAXM17904EVKIT#?

The MAXM17904EVKIT# enables validation of three key reliability features: hiccup-mode overcurrent protection (tested via controlled output short), thermal shutdown at +166°C junction temperature, and robust operation under prebias startup conditions. All tests align with the MAXM17904's specified -40°C to +125°C ambient rating and JESD22 shock/vibration compliance.

Is the MAXM17904EVKIT# RoHS-compliant and lead-free?

Yes - the MAXM17904EVKIT# uses RoHS-compliant components and lead-free soldering processes. The underlying MAXM17904 module carries a "#" suffix indicating full RoHS compliance per Maxim Integrated's packaging standards, and the evaluation board conforms to IPC-J-STD-020 moisture sensitivity level (MSL) 3 handling requirements.
