Analog Devices Inc./Maxim Integrated MAXM17625EVKIT#

Overview

MAXM17625EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to validate the performance of the MAXM17625 10-pin u-SLIC power module in real-world applications. It delivers a fixed 1.5V output at up to 600mA from a 2.7V–5.5V input, operates at 2MHz switching frequency, achieves 92% efficiency at 3.3V_IN/1.5V_OUT/300mA, and supports selectable PWM/PFM mode via jumper configuration - ideal for space-constrained industrial and embedded power subsystem validation.

For engineers reviewing the MAXM17625EVKIT# datasheet, MAXM17625EVKIT# pinout, MAXM17625EVKIT# application, or MAXM17625EVKIT# equivalent, this kit enables rapid characterization of MAXM17625-based buck conversion under thermal stress, light-load efficiency trade-offs, PGOOD monitoring, soft-start behavior, and PCB layout best practices without custom prototyping.

Technical Context

The MAXM17625EVKIT# hosts the MAXM17625 module - a complete, integrated DC-DC step-down power module with internal MOSFETs, controller, compensation, and shielded inductor - configured for 1.5V output using R102/R103 resistor divider. It implements a fixed-frequency current-mode control architecture with internal 1ms soft-start and open-drain PGOOD output referenced to input voltage.

Operation mode (PWM or PFM) is selected via JU102 jumper position; enable state is controlled by JU101. Input filtering uses 2.2μF ceramic + optional 47μF tantalum; output filtering uses 22μF X7R ceramic. The board includes isolated test points for VIN, VOUT, PGND, SGND, EN, MODE, and PGOOD signals.

FAQ

What is the primary function of the MAXM17625EVKIT#?

The MAXM17625EVKIT# is a ready-to-use evaluation platform that demonstrates the electrical performance, thermal behavior, and PCB implementation of the MAXM17625 u-SLIC power module. It allows engineers to verify 1.5V/600mA buck conversion, mode selection (PWM/PFM), PGOOD signaling, and soft-start timing without designing a custom board - directly supporting design-in decisions for the MAXM17625 in final products.

Does the MAXM17625EVKIT# support adjustable output voltage?

No - the MAXM17625EVKIT# is factory-configured for a fixed 1.5V output using precision resistors R102 (33.2kΩ) and R103 (37.4kΩ). While the underlying MAXM17625 module supports 0.8V–1.5V adjustment via external feedback divider, this kit does not include provisions for reconfiguration; users must refer to the MAXM17625 data sheet for adjustable designs.

How is enable and operation mode controlled on the MAXM17625EVKIT#?

Enable is controlled by jumper JU101: shunt position 1–2 connects EN to VIN (enabled), while 2–3 ties EN to GND (disabled). Mode selection uses jumper JU102: shunt 1–2 grounds MODE for forced PWM; no shunt leaves MODE floating for automatic PFM at light load. Default positions are JU101 at 1–2 and JU102 unshunted.

What input and output capacitors are used on the MAXM17625EVKIT#?

The MAXM17625EVKIT# uses a 2.2μF/10V X7R ceramic capacitor (C103) for input filtering, a 22μF/6.3V X7R ceramic capacitor (C104) for output filtering, plus optional 47μF/8V tantalum (C102) and 0.1μF/10V ceramic (C101) for hot-plug and high-frequency noise suppression - all selected per Maxim's validated bill of materials and layout guidelines.

Is the MAXM17625EVKIT# compatible with the MAXM17626 module?

No - the MAXM17625EVKIT# is dedicated to the MAXM17625 module only. Although physically similar and sharing board layout conventions, it is electrically and thermally optimized for the 1.5V/2MHz configuration. The MAXM17626 requires its own evaluation kit (MAXM17626EVKIT#), which uses different feedback resistors, output capacitor value (10μF), and input voltage range (3.6V–5.5V).
