Analog Devices Inc./Maxim Integrated MAXM15064EVKIT#

Overview

The MAXM15064EVKIT# from Maxim Integrated is an evaluation kit designed to accelerate development and validation of the MAXM15064 adjustable-output (0.9V–5V), 300mA, 4.5V–60V input synchronous step-down uSLIC™ power module. It provides a fully assembled, tested reference design with onboard input/output capacitors, feedback resistors, enable/UVLO programming, and power-good monitoring - enabling rapid prototyping for industrial sensors, 4–20mA loop-powered devices, and battery-powered equipment.

For engineers reviewing the MAXM15064EVKIT# datasheet, MAXM15064EVKIT# pinout, MAXM15064EVKIT# application, or MAXM15064EVKIT# equivalent, this kit delivers immediate access to validated thermal performance, load transient response, PFM/PWM mode behavior, soft-start timing, and EMI-compliant layout - critical for time-sensitive power-supply qualification in harsh ambient environments (-40°C to +125°C).

Technical Context

The MAXM15064EVKIT# implements the MAXM15064 power module in its native 10-pin uSLIC™ package (2.6mm × 3mm × 1.5mm), featuring peak-current-mode control, fixed 4.1ms soft-start, and programmable EN/UVLO threshold (1.19V–1.28V rising). It supports both prebias startup and open-drain RESET output with 2ms delay after FB rises above 95.5% of regulation voltage.

The kit enables full characterization of the module's dual operating modes: PWM (fixed ~500kHz) for stable light-to-heavy load regulation, and PFM for ultra-low quiescent current (95μA typ) at light loads - with hiccup overcurrent protection, thermal shutdown at 166°C, and compliance to CISPR22 Class B conducted/radiated emissions when used with recommended filter components.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs high-performance analog, mixed-signal, and power-management ICs for demanding industrial, automotive, and communications applications.

The Himalaya uSLIC™ product line - including the MAXM15064 - was engineered to replace discrete buck regulators and LDOs with fully integrated, compact, thermally robust power modules for space-constrained, high-reliability point-of-load applications.

FAQ

What is the primary function of the MAXM15064EVKIT#?

The MAXM15064EVKIT# is an evaluation kit that provides a ready-to-use hardware platform for testing and validating the MAXM15064 adjustable-output DC-DC power module. It includes all necessary passive components, test points, and layout-optimized PCB to evaluate efficiency, transient response, thermal behavior, and EMI performance - eliminating the need for custom prototyping before final design-in of the MAXM15064.

Does the MAXM15064EVKIT# support both PWM and PFM operation modes?

Yes, the MAXM15064EVKIT# fully supports both modes via the MODE pin: connecting MODE to GND enables fixed-frequency PWM operation (~500kHz) across all loads, while leaving MODE unconnected activates automatic PFM mode at light loads - reducing quiescent current to 95μA typical and improving light-load efficiency, as verified in the MAXM15064EVKIT#'s published efficiency curves.

How is output voltage set on the MAXM15064EVKIT#?

The MAXM15064EVKIT# sets output voltage using an external resistor divider (R1 = 2.2MΩ, R2 = 825kΩ) connected between OUT, FB, and GND - configured for 3.3V out by default. The FB pin regulates to 0.90V (±1.5%), so adjusting R1/R2 allows precise tuning from 0.9V to 5V per the MAXM15064's specification, and the MAXM15064EVKIT# includes solder jumpers to reconfigure for other voltages like 1.5V or 2.5V.

Can the MAXM15064EVKIT# be used to validate thermal performance under real-world conditions?

Yes, the MAXM15064EVKIT# includes thermal vias, copper pour, and footprint alignment matching the MAXM15064's 10-pin uSLIC™ package (θJA = 41.56°C/W on four-layer board), enabling accurate junction temperature measurement up to +150°C. Its layout complies with Maxim's PCB guidelines, and published data shows derated output current vs. ambient temperature - confirming thermal behavior from -40°C to +125°C ambient, as required for industrial and HVAC applications.

Is EMI performance validated on the MAXM15064EVKIT#?

Yes, the MAXM15064EVKIT# includes a documented CISPR22 Class B compliant filter network (0.1µF + 0.68µF input capacitance and 82µH inductor) and publishes conducted/radiated emission plots. Test data confirms compliance at VIN = 24V, VOUT = 5V, IOUT = 300mA - making the MAXM15064EVKIT# a reliable reference for EMI-sensitive designs such as building automation and USB Type-C powered loads.
