Analog Devices Inc./Maxim Integrated MAXM17502EVKIT#

Overview

MAXM17502EVKIT# from Maxim Integrated is an evaluation kit designed to validate and characterize the MAXM17502 1A, 60V step-down power module - a thermally enhanced SiP integrating controller, dual MOSFETs, inductor, and compensation components. It supports adjustable output voltages from 0.9V to 5.0V across 4.5V–60V input, delivers up to 1A, operates from –40°C to +125°C, and enables rapid prototyping of compact, high-efficiency point-of-load supplies for industrial sensors and battery-powered equipment.

For engineers reviewing the MAXM17502EVKIT# datasheet, MAXM17502EVKIT# pinout, MAXM17502EVKIT# application, or MAXM17502EVKIT# equivalent, this kit provides verified thermal resistance data (θ_JA = 30°C/W), pre-validated PCB layout, and full support for evaluating soft-start, EN/UVLO programming, RESET assertion, and load transient response under real-world conditions.

Technical Context

The MAXM17502EVKIT# implements a complete reference design for the MAXM17502 power module, featuring optimized thermal management via exposed pads (EP1/GND, EP2/LX, EP3/OUT), minimal external BOM (only input/output capacitors, feedback resistors, optional SS capacitor), and fixed-frequency PWM operation at 540kHz (typ). It validates the module's integrated peak current limit, thermal shutdown (165°C), and open-drain RESET functionality tied to ±2.5% V_OUT monitoring.

This kit directly supports evaluation of critical system-level behaviors: startup/shutdown sequencing via EN or VIN, prebias startup capability, load regulation accuracy (±8mV/A at 3.3V), and efficiency across input voltages (e.g., 85% at 24V→3.3V/1A). Its layout adheres to strict loop-area minimization rules for IN–PGND, OUT–PGND, and FB routing to ensure EMI compliance and stable closed-loop performance (66.3° phase margin).

FAQ

What is the primary purpose of the MAXM17502EVKIT#?

The MAXM17502EVKIT# is an evaluation kit specifically built to demonstrate, validate, and characterize the MAXM17502 1A, 60V step-down power module. It provides a fully assembled, tested PCB with optimized layout, thermal design, and component selection - enabling engineers to verify electrical performance (efficiency, load/transient response), thermal behavior (θ_JA = 30°C/W), and functional features (soft-start, RESET, EN/UVLO) before committing to custom design.

Does the MAXM17502EVKIT# include the MAXM17502 IC or module?

Yes, the MAXM17502EVKIT# includes one mounted MAXM17502ALI# power module - a 28-pin, 6.5mm × 10mm × 2.8mm SiP containing the controller, dual MOSFETs, shielded inductor, and compensation circuitry. The kit is not a bare PCB; it ships with the module soldered and all critical passives installed per Maxim's recommended design.

Can the MAXM17502EVKIT# be used to evaluate different output voltages?

Yes, the MAXM17502EVKIT# supports adjustable output voltages from 0.9V to 5.0V by changing the external feedback resistor divider (R1/R2) connected to the FB pin. The kit's documentation provides exact resistor values for common outputs (e.g., 1.2V, 3.3V, 5V) in Table 1, and the MAXM17502's 0.9V internal reference ensures ±1.8% system accuracy across the range.

How does the MAXM17502EVKIT# support thermal design verification?

The MAXM17502EVKIT# was used to measure the MAXM17502's junction-to-ambient thermal resistance (θ_JA = 30°C/W), as explicitly stated in Note 1 of the datasheet. Its layout implements all thermal best practices: direct connection of EP1 (GND), EP2 (LX), and EP3 (OUT) to large copper areas; no solder mask on exposed pads; and optimized via placement - allowing users to replicate and validate thermal performance in their own systems.

Is the MAXM17502EVKIT# compatible with other Himalaya modules?

No - the MAXM17502EVKIT# is specific to the MAXM17502 module. While the MAXM17502 shares pin-to-pin compatibility with other Himalaya modules (e.g., MAXM17503, MAXM17504), each has unique electrical characteristics (current rating, voltage range, frequency) and requires its own evaluation kit. The MAXM17502EVKIT# layout, component values, and test points are optimized exclusively for the 1A/60V MAXM17502.
