Analog Devices Inc./Maxim Integrated MAX17625EVKIT#

Overview

MAX17625EVKIT# from Analog Devices is an evaluation kit designed to validate the performance of the MAX17625 and MAX17626 synchronous step-down DC-DC converters. It supports input voltages from 2.7V to 5.5V, delivers up to 700mA output current, and features preconfigured 1.2V (MAX17625) and 3.3V (MAX17626) outputs with fixed 2MHz and 4MHz switching frequencies respectively. The kit enables rapid assessment of efficiency, PGOOD signaling, and PWM/PFM mode selection in power-constrained embedded systems.

For engineers reviewing the MAX17625EVKIT# datasheet, MAX17625EVKIT# pinout, MAX17625EVKIT# application, or MAX17625EVKIT# equivalent, this fully assembled board provides verified layout, selectable operation modes, soft-start timing, and real-world load testing capability - all critical for validating buck converter integration in space- and thermally-sensitive designs.

Technical Context

The MAX17625EVKIT# hosts two electrically isolated evaluation circuits on a single PCB: one for the MAX17625 (1.2V/700mA/2MHz) and one for the MAX17626 (3.3V/700mA/4MHz). Each circuit includes dedicated input/output pads, jumper-selectable EN and MODE control, and integrated PGOOD pull-up resistors tied to respective input rails.

It implements proven component selection including Murata DFE252012F inductors, TDK/X7R ceramic capacitors (C106 = 22µF/6.3V for MAX17625; C206 = 10µF/10V for MAX17626), and Kemet T520B476M008ATE035 tantalum damping capacitors for hot-plug stability. Jumper configurations (JU101/JU201 for EN; JU102/JU202 for PWM/PFM) provide direct hardware-level control without firmware.

FAQ

What does the MAX17625EVKIT# evaluate?

The MAX17625EVKIT# evaluates both the MAX17625 and MAX17626 synchronous step-down DC-DC converters. It provides two independent, fully assembled circuits on one PCB: one configured for 1.2V/700mA/2MHz operation (MAX17625), and another for 3.3V/700mA/4MHz operation (MAX17626). Each includes dedicated input/output test points, jumper-selectable enable and mode control, and PGOOD monitoring - enabling immediate functional validation without additional components or layout effort. The MAX17625EVKIT# is not a standalone IC but a ready-to-use evaluation platform.

Does the MAX17625EVKIT# support adjustable output voltage?

Yes, the MAX17625EVKIT# supports output voltage adjustment via external resistor dividers. The MAX17625 section uses R101 (18.7kΩ) and R102 (37.4kΩ) to set its default 1.2V output, covering the full 0.8V–1.5V range. The MAX17626 section uses R201 (118kΩ) and R202 (37.4kΩ) for its default 3.3V output, supporting 1.5V–3.3V. These dividers allow engineers to reconfigure the MAX17625EVKIT# for custom voltage rails without modifying the PCB layout or replacing the ICs.

How is enable and mode control implemented on the MAX17625EVKIT#?

Enable and mode control on the MAX17625EVKIT# are implemented via solder-jumpers: JU101/JU201 select EN logic level (shunt 1–2 connects EN to VIN for enable; 2–3 connects to GND for disable), while JU102/JU202 configure operation mode (shunt 1–2 grounds MODE for forced PWM; open position enables automatic PFM at light load). These jumpers provide deterministic, hardware-based control - eliminating dependency on external controllers or firmware during bench evaluation of the MAX17625EVKIT#.

What input and output capacitors are used on the MAX17625EVKIT#?

The MAX17625EVKIT# uses Murata GRM188R71A225KE15 (2.2µF/10V X7R) for input capacitance on both channels. For output, it uses Murata GRM21BZ70J226ME44 (22µF/6.3V X7R) on the MAX17625 side and Murata GRM188Z71A106KA73 (10µF/10V X7R) on the MAX17626 side. Optional Kemet T520B476M008ATE035 (47µF/8V tantalum) capacitors are included for damping input transients during hot-plug events - a key reliability feature validated on the MAX17625EVKIT#.

Is the MAX17625EVKIT# fully assembled and tested?

Yes, the MAX17625EVKIT# is fully assembled and factory-tested. It ships with both MAX17625ATA+ and MAX17626ATA+ ICs mounted in TDFN-8-EP packages, all passive components populated (including input/output capacitors, inductors, and precision feedback resistors), and silkscreen-marked test points for VIN, VOUT, EN, MODE, and PGOOD. No soldering or component placement is required - engineers can power the MAX17625EVKIT# directly using a 2.7V–5.5V DC supply and begin performance characterization immediately.
