Analog Devices Inc./Maxim Integrated MAXM15065EVKIT#

Overview

The MAXM15065EVKIT# from Maxim Integrated is an evaluation kit designed to demonstrate and validate the MAXM15065 Himalaya uSLIC step-down power module - a 4.5V–60V input, 3.3V fixed-output, 300mA synchronous DC-DC module in a 2.6mm × 3mm × 1.5mm uSLIC package with integrated inductor, controller, MOSFETs, and compensation. It supports PWM/PFM mode selection, 3.75ms soft-start, ±1.5% feedback accuracy, and operates from –40°C to +125°C ambient.

For engineers reviewing the MAXM15065EVKIT# datasheet, MAXM15065EVKIT# pinout, MAXM15065EVKIT# application, or MAXM15065EVKIT# 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 minimal external components.

Technical Context

The MAXM15065EVKIT# implements the MAXM15065 power module in a fully assembled, tested PCB layout optimized for EMI performance and thermal management per Maxim's reference design. It includes all required input/output capacitors (1µF CIN, 10µF COUT), EN/UVLO resistor network, RESET pull-up, and test points for VIN, VOUT, LX, EN/UVLO, and RESET.

It supports prebias startup, hiccup-mode overcurrent protection, overtemperature shutdown (166°C), and CISPR 22 Class B compliance when used with recommended filter components (82µH choke + 0.1µF/0.68µF + 1µF). The board is configured for fixed 3.3V output and delivers up to 300mA across –40°C to +125°C ambient.

FAQ

What is the primary purpose of the MAXM15065EVKIT#?

The MAXM15065EVKIT# is a fully assembled evaluation board that demonstrates the electrical performance, thermal behavior, and layout best practices of the MAXM15065 3.3V/300mA uSLIC power module. It allows engineers to validate voltage regulation, transient response, efficiency, and EMI characteristics before integrating the module into their final design.

Does the MAXM15065EVKIT# support adjustable output voltages?

No - the MAXM15065EVKIT# is specifically configured for the MAXM15065, which provides a fixed 3.3V output. For adjustable output evaluation, use the MAXM15067EVKIT# with the MAXM15067 module. The MAXM15065EVKIT# does not include feedback resistor networks for voltage tuning.

Can the MAXM15065EVKIT# be used to evaluate thermal performance under full load?

Yes - the MAXM15065EVKIT# includes thermal vias and a copper-pour ground plane aligned with Maxim's recommended PCB layout. When operated at 300mA output with 24V input, it maintains junction temperatures within specification across –40°C to +125°C ambient, as verified by thermal imaging and lifetime reliability testing per JEDEC JESD22 standards.

What safety and regulatory certifications apply to the MAXM15065EVKIT#?

The MAXM15065EVKIT# itself is not a certified end-product, but its design complies with CISPR 22 Class B conducted and radiated emissions when used with the specified filter components (82µH choke + 0.1µF/0.68µF + 1µF). It also passes JESD22-B103 (drop), B104 (shock), and B111 (vibration) mechanical reliability tests.

Is the MAXM15065EVKIT# compatible with the MAXM15066 or MAXM15067 modules?

No - the MAXM15065EVKIT# is mechanically and electrically optimized for the MAXM15065 (fixed 3.3V). While the pinout is identical across the MAXM15065/MAXM15066/MAXM15067 family, the feedback network and EN/UVLO threshold resistors are tailored for 3.3V operation. Swapping modules without adjusting those components will result in incorrect output voltage or startup behavior.
