Analog Devices Inc./Maxim Integrated MAXM17572EVKIT#

Overview

MAXM17572EVKIT# from Analog Devices is an evaluation kit designed to validate the MAXM17572 high-voltage synchronous step-down DC-DC power module in a fixed 5V/1A output configuration, operating from 7V–60V input with 900kHz switching frequency and CISPR32 Class B EMI compliance.

For engineers reviewing the MAXM17572EVKIT# datasheet, MAXM17572EVKIT# pinout, MAXM17572EVKIT# application, or MAXM17572EVKIT# equivalent, this kit supports rapid validation of input UVLO programming, soft-start timing, RESET signal behavior, external clock synchronization, and efficiency measurement across load and line conditions.

Technical Context

The MAXM17572EVKIT# implements the MAXM17572 uSLIC™ power module (12-pin, 6mm × 9mm × 1.8mm) in a fully assembled, tested PCB layout optimized for low-noise 5V regulation. It integrates programmable EN/UVLO via R2–R3 divider (7V turn-on default), 1ms soft-start via 5.6nF SS capacitor, and EXTVCC bootstrapping via JU1 jumper.

Key design features include open-drain RESET monitoring, RT/SYNC pad for external clock synchronization (1.1×–1.4× f_SW), and bottom-layer footprints for optional EMI filter components (L1, C8) enabling CISPR32 Class B conducted/radiated emissions compliance without layout modification.

FAQ

What is the primary function of the MAXM17572EVKIT#?

The MAXM17572EVKIT# is a fully assembled evaluation kit that demonstrates and validates the operation of the MAXM17572 synchronous step-down power module. It delivers a regulated 5V/1A output from a 7V–60V input, featuring programmable UVLO, 1ms soft-start, open-drain RESET, and external frequency synchronization - all implemented on a proven, EMI-optimized PCB layout.

Does the MAXM17572EVKIT# support adjustable output voltage?

No - the MAXM17572EVKIT# is factory-configured for fixed 5V output using R7 (118kΩ) and R8 (25.5kΩ) feedback resistors. While the underlying MAXM17572 module supports 0.9V–12V adjustment, this specific EV kit variant is not user-reconfigurable for other voltages without modifying the feedback network and recalibrating compensation.

How is EMI compliance achieved on the MAXM17572EVKIT#?

The MAXM17572EVKIT# meets CISPR32 Class B conducted and radiated emissions limits by integrating optimized PCB layout techniques and provision for an external EMI filter: cuttable trace at L1 location and footprint for 10µH inductor + 1µF capacitor (C8). With these components installed, test data confirms emissions remain below both peak and average Class B limits.

What power supply requirements are needed to operate the MAXM17572EVKIT#?

A 0–60V, 2A DC power supply is required. Input must be applied between VIN_EMI and GND pads. The kit accepts input from 7.0V minimum (due to UVLO setting) up to 60V maximum. A resistive load capable of sinking 1.0A is recommended for full-load testing, and four DMMs are advised for simultaneous monitoring of VIN, VOUT, EN/UVLO, and RESET signals.

Can the MAXM17572EVKIT# be synchronized to an external clock?

Yes - the MAXM17572EVKIT# provides an accessible RT/SYNC pad that accepts an external clock signal within 1.1× to 1.4× the internal 900kHz switching frequency (i.e., 990kHz–1.26MHz). This enables precise timing alignment with system clocks or noise-sensitive subsystems, reducing beat frequencies and improving spectral performance in multi-rail applications.
