Analog Devices Inc./Maxim Integrated MAXM15466EVKIT#

Overview

The MAXM15466EVKIT# from Maxim Integrated is an evaluation kit designed to accelerate development and validation of the MAXM15466 fixed 5V, 300mA synchronous step-down uSLIC™ power module - a fully integrated DC-DC solution with controller, MOSFETs, compensation, and inductor in a 2.6mm × 3mm × 1.5mm package, operating from 4.5V to 42V input.

For engineers reviewing the MAXM15466EVKIT# datasheet, MAXM15466EVKIT# pinout, MAXM15466EVKIT# application, or MAXM15466EVKIT# equivalent, this kit enables rapid prototyping of industrial sensors, 4–20mA loop-powered devices, and USB Type-C loads requiring compact, high-efficiency, low-noise point-of-load regulation with pre-validated layout and thermal performance.

Technical Context

The MAXM15466EVKIT# implements the MAXM15466 power module in its production-ready reference configuration: fixed 5V output, 300mA capability, peak-current-mode control, and 550kHz switching frequency. It includes all required external components - input/output capacitors, feedback resistors (for fixed output), EN/UVLO resistor divider, and RESET pull-up - on a compact PCB with optimized thermal vias and ground plane.

It supports full functional validation including soft-start (3.75ms), PFM/PWM mode selection via MODE pin, open-drain RESET monitoring, programmable EN/UVLO threshold (1.215V typ), and hiccup-mode overcurrent protection. The board complies with CISPR22 Class B conducted/radiated emissions when used with recommended filter components.

Manufacturer

Maxim Integrated (now part of Analog Devices) is a semiconductor company specializing in high-performance analog, mixed-signal, and power management solutions for industrial, automotive, and communications applications.

The Himalaya uSLIC™ product line - including the MAXM15466 - was engineered to replace discrete buck regulators and LDOs with fully integrated, ultra-compact, thermally robust power modules for harsh-environment and size-critical embedded systems.

FAQ

What is the primary function of the MAXM15466EVKIT#?

The MAXM15466EVKIT# is a fully assembled evaluation board that demonstrates and validates the MAXM15466 fixed 5V, 300mA synchronous step-down uSLIC™ power module. It provides immediate hardware access to all pins, pre-populated input/output filtering, thermal management features, and documented test points - enabling engineers to verify voltage regulation, efficiency, transient response, and EMI behavior without custom PCB design. The MAXM15466EVKIT# directly supports rapid integration into industrial and portable power architectures.

Does the MAXM15466EVKIT# support adjustable output voltages?

No - the MAXM15466EVKIT# is configured exclusively for the MAXM15466 device, which delivers a factory-trimmed fixed 5V output. It does not support output adjustment; the feedback network is internally set and no external resistors are provided for VOUT tuning. For adjustable output evaluation, the MAXM15467EVKIT# (supporting 0.9V–6.3V) must be used. The MAXM15466EVKIT# pinout and layout are optimized for fixed 5V operation only.

Can the MAXM15466EVKIT# be used to evaluate thermal performance under full load?

Yes - the MAXM15466EVKIT# includes a 4-layer PCB with dedicated thermal vias beneath the uSLIC™ module's exposed pad, a solid ground plane, and copper pours sized per Maxim's thermal guidelines. It has been characterized delivering 300mA continuously at 42V input and 5V output across −40°C to +125°C ambient, with junction temperature monitored via on-board thermal sensors. Full thermal images and derating curves are published in the MAXM15466EVKIT# user guide.

What EMI filtering components are included on the MAXM15466EVKIT#?

The MAXM15466EVKIT# integrates a CISPR22 Class B-compliant input filter: an 82µH shielded inductor, 0.1µF + 0.68µF ceramic input capacitors, and 1µF output capacitor. This filter reduces both differential- and common-mode noise, enabling pass/fail compliance testing per EN55022 without additional external components. Layout follows Maxim's strict EMI-reduction practices, including minimized high-di/dt loops and controlled impedance routing - all verified during MAXM15466EVKIT# qualification.

Is the MAXM15466EVKIT# compatible with the MAXM15465 or MAXM15467 modules?

No - the MAXM15466EVKIT# is mechanically and electrically optimized for the MAXM15466 only. While the three modules share the same 10-pin uSLIC™ package and pinout, the MAXM15466EVKIT# uses fixed 5V feedback and lacks the external resistor network needed for the MAXM15467's adjustable output or the MAXM15465's 3.3V setting. Swapping modules requires rework of feedback components and validation of loop stability - thus, each variant has its own dedicated evaluation kit: MAXM15465EVKIT# and MAXM15467EVKIT#.
