Analog Devices Inc./Maxim Integrated MAXM15465EVKIT#

Overview

MAXM15465EVKIT# from Maxim Integrated is an evaluation kit for the MAXM15465 Himalaya uSLIC™ synchronous step-down power module, designed to simplify validation of 3.3V/300mA DC-DC conversion from 4.5V–42V input in space-constrained industrial and battery-powered systems. It supports fixed-output operation, soft-start, power-good monitoring, and prebias startup.

For engineers reviewing the MAXM15465EVKIT# datasheet, MAXM15465EVKIT# pinout, MAXM15465EVKIT# application, or MAXM15465EVKIT# equivalent, this kit enables rapid prototyping of high-efficiency, low-noise point-of-load regulation with integrated inductor and full thermal/emission compliance verification.

Technical Context

The MAXM15465EVKIT# implements the MAXM15465 power module-a fully integrated 10-pin uSLIC™ device featuring peak-current-mode control, internal compensation, and selectable PWM/PFM operation. It delivers up to 300mA at ±1.5% output voltage accuracy across –40°C to +125°C ambient.

Key design elements include a fixed 3.75ms soft-start, open-drain RESET output with 95.5%/92% FB threshold hysteresis, programmable EN/UVLO (1.215V typ), and robust hiccup overcurrent + thermal shutdown (166°C). The board validates CISPR22 Class B conducted/radiated emissions compliance using integrated filter components.

FAQ

What is the primary function of the MAXM15465EVKIT#?

The MAXM15465EVKIT# is an evaluation kit for the MAXM15465 uSLIC™ power module, enabling engineers to validate 3.3V/300mA step-down conversion from 4.5V–42V input. It provides a fully assembled, tested PCB with input/output filtering, RESET monitoring, and EN/UVLO configuration-allowing immediate functional and thermal testing of the MAXM15465 in real-world conditions.

Does the MAXM15465EVKIT# support adjustable output voltages?

No. The MAXM15465EVKIT# is configured specifically for the MAXM15465, which is a fixed 3.3V output variant. For adjustable outputs (0.9V–6.3V), the MAXM15467EVKIT# must be used. The MAXM15465EVKIT# does not include feedback resistor networks or jumpers for VOUT adjustment.

Can the MAXM15465EVKIT# be used to evaluate EMI performance?

Yes. The MAXM15465EVKIT# incorporates the recommended CISPR22 Class B filter (0.1µF + 0.68µF ceramic + 82µH choke + 1µF output cap) and has been characterized per EN55022. Radiated and conducted emission plots are published in the MAXM15465 datasheet, making the kit suitable for pre-compliance EMI validation in end-equipment designs.

What thermal performance can be expected from the MAXM15465 on the MAXM15465EVKIT#?

On the MAXM15465EVKIT#, the MAXM15465 delivers full 300mA output up to +125°C ambient temperature when mounted on a standard four-layer board with natural convection. Thermal shutdown activates at +166°C junction temperature, with 10°C hysteresis, ensuring safe operation under sustained load in enclosed industrial enclosures.

Is prebias startup supported on the MAXM15465EVKIT#?

Yes. The MAXM15465EVKIT# supports prebias startup-verified in the datasheet's oscilloscope waveforms (e.g., toc63, toc64). When the output is precharged (e.g., to 2V), the MAXM15465 safely starts without reverse current or output overshoot, making it suitable for hot-swap and redundant power rail applications.
