Analog Devices Inc./Maxim Integrated MAX17541GTAEVKIT#

Overview

MAX17541GTAEVKIT# 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, fixed 600kHz switching frequency, and integrated high-side pMOS/low-side nMOS power switches in a 3mm × 2mm TDFN package. It validates thermal performance up to +125°C ambient and supports prebiased start-up, hiccup-mode overcurrent protection, and output voltage monitoring via open-drain RESET.

For engineers reviewing the MAX17541GTAEVKIT# datasheet, MAX17541GTAEVKIT# pinout, MAX17541GTAEVKIT# application, or MAX17541GTAEVKIT# equivalent, this kit enables rapid validation of industrial point-of-load designs requiring ultra-small footprint, high efficiency (>90% at 500mA), low shutdown current (0.9µA), and robust operation across -40°C to +125°C ambient.

Technical Context

The MAX17541GTAEVKIT# implements the MAX17541G IC in a fully assembled, tested reference design featuring a 47µH shielded inductor (XFL6060-473 or 74404054470), all-ceramic input/output capacitors (1µF CIN, 10µF COUT), and precision feedback resistors (R4 = 82.5kΩ, R5 = 18.2kΩ) configured for 5V output. It incorporates the IC's peak-current-mode control architecture, internal 5V VCC LDO, and external RC compensation network (RZ/CZ/CP) tuned for 53.6kHz crossover and 56.9° phase margin.

This kit directly supports evaluation of critical system-level behaviors: soft-start timing (via 3300pF SS capacitor), RESET assertion at 92.5% VOUT, hiccup timeout after single runaway current-limit event (32,768 cycles), and conducted EMI performance with integrated input filter (2.2µF + 4.7µH). Layout follows Maxim's PCB guidelines-separate analog/power grounds tied at VCC bypass, thermal vias under EP, and minimized high-di/dt loop area.

FAQ

What is the primary function of the MAX17541GTAEVKIT#?

The MAX17541GTAEVKIT# is a fully assembled evaluation kit for the MAX17541G synchronous step-down DC-DC converter. It demonstrates a complete 5V/500mA power solution operating from 4.5V–42V input, featuring validated layout, thermal design, and protection functionality-including hiccup-mode overcurrent response, RESET monitoring, and prebiased startup-enabling immediate lab validation of industrial power architectures.

Does the MAX17541GTAEVKIT# support adjustable output voltages?

Yes-the MAX17541GTAEVKIT# is configured for 5V output using R4 = 82.5kΩ and R5 = 18.2kΩ, but the underlying MAX17541G IC supports adjustable outputs from 0.9V to 92% VIN. Users can modify the FB divider to set alternate voltages (e.g., 3.3V using R4 = 48.7kΩ, R5 = 18.2kΩ per Figure 5), maintaining full regulation accuracy (±1.7%) and stability across the industrial temperature range.

How does the MAX17541GTAEVKIT# handle overcurrent conditions?

The MAX17541GTAEVKIT# implements the MAX17541G's dual-stage overcurrent protection: cycle-by-cycle peak limiting at 0.76A (typ) and runaway current limiting at 0.78A (typ). A single runaway event triggers hiccup mode-32,768 clock cycles of shutdown followed by automatic soft-start retry-minimizing power dissipation during sustained faults while preserving reliability in industrial overload scenarios.

What thermal validation is provided with the MAX17541GTAEVKIT#?

The MAX17541GTAEVKIT# is built on a multilayer PCB matching JEDEC JESD51-7 thermal test conditions, confirming operation at +125°C ambient with junction temperatures held below +150°C. Its layout includes thermal vias under the exposed pad and optimized copper pours, validating the MAX17541G's θJA = 67.3°C/W and enabling accurate thermal modeling for end-equipment enclosure integration.

Can the MAX17541GTAEVKIT# be used for EMI compliance testing?

Yes-the MAX17541GTAEVKIT# includes an integrated input filter (2.2µF ceramic + 4.7µH choke) and has published conducted EMI data (average/peak limits per CISPR 22/EN55022) up to 30MHz. Its layout adheres to Maxim's EMI-reduction guidelines, making it suitable for pre-compliance screening of input filter effectiveness and layout-sensitive noise coupling in industrial power supplies.
