Analog Devices Inc./Maxim Integrated MAX17541GTBEVKIT#

Overview

MAX17541GTBEVKIT# from Maxim Integrated is an evaluation kit for the MAX17541G synchronous step-down DC-DC converter, designed to demonstrate 5V/500mA operation with 4.5V–42V input range, 600kHz fixed-frequency PWM control, ±1.7% output voltage regulation over –40°C to +125°C, and integrated high-side pMOS/low-side nMOS power switches in a 3mm × 2mm TDFN package.

For engineers reviewing the MAX17541GTBEVKIT# datasheet, MAX17541GTBEVKIT# pinout, MAX17541GTBEVKIT# application, or MAX17541GTBEVKIT# equivalent, this kit provides validated reference design, conducted EMI test data (per CISPR 22), thermal performance metrics (θ_JA = 67.3°C/W), and preconfigured 5V output circuitry using XFL6060-473 or 74404054470 inductors, enabling rapid prototyping of industrial point-of-load supplies.

Technical Context

The MAX17541GTBEVKIT# implements peak-current-mode control with fixed 600kHz switching frequency, internal 5V LDO (VCC) for gate drive, and hiccup-mode overcurrent protection triggered by either 0.78A runaway current limit or V_OUT dropping below 71.14% of nominal. It supports prebiased startup and adjustable soft-start via external capacitor on SS pin.

Key validation features include built-in RESET open-drain output (active-low at 92.5% V_FB, rising after 1024 cycles at 95.5% V_FB), programmable EN/UVLO threshold (1.218V typical rising), and thermal shutdown at 165°C with 10°C hysteresis - all verified per the MAX17541G production IC's electrical characteristics and operating curves.

FAQ

What is the primary function of the MAX17541GTBEVKIT#?

The MAX17541GTBEVKIT# is an evaluation kit for the MAX17541G synchronous step-down DC-DC converter. It provides a fully assembled and tested PCB implementing a 5V/500mA output from 4.5V–42V input, featuring the exact MAX17541G IC in its 10-pin TDFN package, validated layout, and documented EMI/thermal performance - enabling immediate hardware validation and design reuse.

Does the MAX17541GTBEVKIT# support adjustable output voltages?

No - the MAX17541GTBEVKIT# is configured for fixed 5V output per the application circuit in Figure 6 of the MAX17541G datasheet. While the underlying MAX17541G IC supports adjustable outputs from 0.9V to 92% VIN via FB resistor divider, the evaluation kit uses R4 = 82.5kΩ and R5 = 18.2kΩ to set 5V and does not include provisions for reconfiguration.

Which inductors are validated on the MAX17541GTBEVKIT# board?

The MAX17541GTBEVKIT# supports two validated inductors: Würth Elektronik XFL6060-473 (47µH, shielded, 1.2A saturation) and Würth 74404054470 (47µH, shielded, 1.2A saturation). Both meet the required ISAT > 0.76A and R_DCR specifications for stable 500mA operation with <1% output ripple.

How is EMI performance characterized for the MAX17541GTBEVKIT#?

Conducted EMI measurements for the MAX17541GTBEVKIT# were performed per CISPR 22 using an input filter comprising C_IN = 2.2µF, L_IN = 4.7µH, and an additional 2.2µF ceramic capacitor. The kit meets both average and quasi-peak limits up to 30MHz, confirming suitability for industrial EMC requirements without added filtering.

What thermal metrics are provided for the MAX17541GTBEVKIT#?

The MAX17541GTBEVKIT# leverages the MAX17541G's thermal characteristics: θ_JA = 67.3°C/W and θ_JC = 18.2°C/W on a multilayer board. Measured junction temperature rise remains below 60°C at 500mA/5V output with 24V input, validating operation within the –40°C to +125°C ambient range without forced airflow.
