Analog Devices Inc./Maxim Integrated MAX17502GTEVKIT#

Overview

MAX17502GTEVKIT# from Maxim Integrated is an evaluation kit for the MAX17502G ultra-small, high-efficiency synchronous step-down DC-DC converter - a 60V input, 1A adjustable-output (0.9V to 92%VIN) regulator in 10-pin TDFN (3mm × 2mm). It supports fixed-frequency peak-current-mode control at 600kHz, delivers ±1.7% output voltage accuracy over –40°C to +125°C, and integrates high-side pMOS and low-side nMOS switches with R_DS(ON) of 0.85Ω/0.35Ω (typ), enabling compact industrial power supplies.

For engineers reviewing the MAX17502GTEVKIT# datasheet, MAX17502GTEVKIT# pinout, MAX17502GTEVKIT# application, or MAX17502GTEVKIT# equivalent, this kit provides validated reference design, thermal performance characterization, conducted EMI test data (per CISPR 22), load transient waveforms, Bode plots, and preconfigured 3.3V/5V/adjustable output configurations - essential for rapid prototyping of high-voltage PoL converters in harsh environments.

Technical Context

The MAX17502GTEVKIT# implements the MAX17502G IC in a fully assembled, tested PCB layout optimized for minimal footprint and thermal performance: it uses all-ceramic capacitors, a 10µH shielded inductor, and leverages the IC's internal compensation for fixed 3.3V/5V outputs or external RC network for adjustable versions. The board integrates EN/UVLO resistor divider, soft-start capacitor (3300pF), and open-drain RESET pull-up - directly exposing key control nodes (SS, COMP, FB/VO, EN/UVLO) for system-level tuning.

It demonstrates critical protection behaviors including hiccup-mode current limiting (triggered at 1.7A runaway limit), thermal shutdown at +165°C (10°C hysteresis), and prebiased start-up - all verified across –40°C to +125°C ambient. Conducted EMI testing per Figure 27 confirms compliance with CISPR 22 Class B limits using only the onboard 2.2µF C_IN and 10µH L_IN filter.

FAQ

What is the primary function of the MAX17502GTEVKIT#?

The MAX17502GTEVKIT# is an evaluation kit designed exclusively to demonstrate and validate the MAX17502G synchronous step-down DC-DC converter. It provides a fully assembled PCB with optimized layout, preselected passive components (inductor, input/output capacitors), and accessible test points for EN/UVLO, SS, FB/VO, COMP, and RESET - enabling engineers to verify electrical performance, thermal behavior, EMI, and protection features before custom design integration.

Does the MAX17502GTEVKIT# support adjustable output voltage?

Yes - the MAX17502GTEVKIT# is configured for the MAX17502G variant, which supports adjustable output from 0.9V to 92% of input voltage. The board includes solder jumpers and resistor pads to configure feedback dividers, and the COMP pin is routed for external RC compensation as required for stability in adjustable-output mode per the MAX17502G datasheet Section "External Loop Compensation."

Can the MAX17502GTEVKIT# be used to evaluate other MAX17502 variants like MAX17502E or MAX17502F?

No - the MAX17502GTEVKIT# is specifically tailored for the MAX17502G (adjustable output) variant. While the board shares the same core layout and component footprints, fixed-output versions (MAX17502E/F) require different feedback networks and lack COMP pin routing for external compensation. Evaluation of those variants requires their respective kits: MAX17502EFEVKIT# or MAX17502FFEVKIT#.

What EMI test data is included with the MAX17502GTEVKIT#?

The MAX17502GTEVKIT# documentation includes conducted EMI test results per CISPR 22 Class B (Figure 27), measured using the onboard input filter (C_IN = 2.2µF, L_IN = 10µH). Peak and average emissions are shown across 150kHz–30MHz, confirming compliance without additional filtering - critical for industrial and telecom power supply certification workflows.

How does the MAX17502GTEVKIT# demonstrate thermal performance?

The MAX17502GTEVKIT# validates thermal behavior through published temperature rise measurements under full-load conditions and explicit thermal shutdown testing at +165°C junction (Figure 24). Its compact TDFN-10 layout uses the exposed pad thermally connected to a large internal copper plane, achieving θ_JA = 67.3°C/W (multilayer board), enabling reliable operation up to +125°C ambient as confirmed in the datasheet's thermal characterization section.
