Analog Devices Inc./Maxim Integrated MAX20499CEVKIT#

Overview

MAX20499CEVKIT# from Analog Devices is a fully assembled and tested evaluation kit designed to demonstrate the MAX20499C 16A automotive-grade step-down DC-DC converter. It supports 3V–5.5V input, delivers 0.5V–1.275V output, operates at 2.2MHz fixed-frequency PWM, and enables I²C-based dynamic voltage adjustment with programmable slew rate and soft-start.

For engineers reviewing the MAX20499CEVKIT# datasheet, MAX20499CEVKIT# pinout, MAX20499CEVKIT# application, or MAX20499CEVKIT# equivalent, this kit provides validated hardware for evaluating load transient response, Bode plot characterization, differential remote sensing, spread-spectrum EMI reduction, and I²C configuration of the MAX20499C/MAX20499D regulators in high-current power delivery systems.

Technical Context

The MAX20499CEVKIT# implements a complete buck converter reference design centered on the MAX20499C IC, featuring integrated 70nH power inductor (L1), all-ceramic output capacitance (including 47µF ×8 X7T 1206 and 470µF polymer tantalum), and differential voltage sense routing to J10 (RS+/RS−). Input is applied via banana jacks TP1 (PV) and TP2 (GND), while output is accessible at TP3 (VOUT) and TP4 (GND).

It includes dedicated test points for EN (J2), RESETB (J8), SDA/SCL (J6/J7), SYNC (J3/J4), Bode+/- (J27/J28), and LX (J26), plus a 20-pin header (J1) for optional I²C interface boards like MINIQUSB. The board supports both factory-preset and I²C-programmable operation, and allows frequency reconfiguration via external SYNC signal or jumper-modified internal selection.

FAQ

What does the MAX20499CEVKIT# evaluate?

The MAX20499CEVKIT# evaluates the MAX20499C and MAX20499D 16A step-down DC-DC regulators. It provides a ready-to-use platform for validating efficiency, load transient behavior, thermal performance, I²C programmability, and spread-spectrum EMI reduction. The board ships fully assembled with verified layout and calibrated test points, enabling immediate bench testing without additional hardware setup.

Can the MAX20499CEVKIT# be used to evaluate the MAX20499D?

Yes, the MAX20499CEVKIT# explicitly supports evaluation of both the MAX20499C and MAX20499D. As stated in the official documentation, the MAX20499D can be evaluated by replacing the preinstalled U1 (MAX20499C) with the MAX20499D IC. All circuitry, test points, and firmware interfaces remain compatible between the two variants.

Does the MAX20499CEVKIT# include an I²C interface board?

No, the MAX20499CEVKIT# does not include an I²C interface board. It features a 20-pin female header (J1) and test points J6 (SDA) and J7 (SCL) for connecting optional interface modules such as the MINIQUSB or MAXPICO2MINIQ# boards. Users must procure and connect a compatible I²C adapter separately to access dynamic voltage control and telemetry functions.

What power supply is required to operate the MAX20499CEVKIT#?

A 5V, 20A capable power supply is required to operate the MAX20499CEVKIT# under full 16A load conditions. Input is applied across banana jacks TP1 (PV) and TP2 (GND). The board also supports 3V–5.5V input per the MAX20499C specification, but 5V is recommended for optimal margin and thermal performance during evaluation.

How is the MAX20499CEVKIT# enabled and monitored?

The MAX20499CEVKIT# is enabled by placing a jumper across J5 (EN to PV). Enable status is monitored at test point J2, RESETB at J8, and SYNC at J3/J4. Output voltage is measured differentially at J10 (RS+) and J9 (RS−), while VOUT is accessible at banana socket TP3. All critical signals are routed to labeled test points for oscilloscope or multimeter access.
