Analog Devices Inc./Maxim Integrated MAX17554BEVKIT#

Overview

MAX17554BEVKIT# from Analog Devices is a fully assembled and tested evaluation kit for the MAX17554B 10V–60V input, 5V/50mA synchronous step-down DC-DC converter in an 8-pin TDFN (2mm × 2mm) package. It delivers 78.3% light-load efficiency at 48V_IN/5V_OUT/10mA and features fixed 70kHz switching, hiccup-mode protection, and CISPR32 Class B compliance.

For engineers reviewing the MAX17554BEVKIT# datasheet, MAX17554BEVKIT# setup, MAX17554BEVKIT# application, or MAX17554BEVKIT# configuration, this page provides verified board-level performance data, EMI filter footprint guidance, hot-plug input protection details, and validated test procedures for industrial power supply validation.

Technical Context

The MAX17554BEVKIT# implements a fixed-frequency (70kHz), internally compensated buck topology with built-in soft-start (0.8ms typ), thermal shutdown, and hiccup-mode overcurrent protection. Input voltage turn-on is fixed at ≤42.5V and turn-off at ≤10V.

It supports input ranges from 10V to 60V and delivers regulated 5V output up to 50mA. The PCB includes optional C5 (22μF electrolytic) to dampen LC oscillations during hot-plug events with long input cables, and designated footprints for CISPR32 Class B conducted EMI filtering.

FAQ

What is the primary function of the MAX17554BEVKIT#?

The MAX17554BEVKIT# is a fully assembled evaluation kit designed to validate the electrical performance, protection features, and layout implementation of the MAX17554B synchronous step-down DC-DC converter. It enables rapid bench testing of 10V–60V input to 5V/50mA output conversion, including hiccup-mode overload response, thermal shutdown behavior, and CISPR32 Class B EMI performance when configured with optional filter components.

Does the MAX17554BEVKIT# require external components to operate?

No - the MAX17554BEVKIT# is fully assembled and tested with all required components installed, including C1, C4, C5, C6, C10, R6, L1, and U1 (MAX17554BATA+). Only a 60V adjustable DC power supply and a 5V load (up to 50mA) are needed for basic operation. Optional EMI filter parts (L2, C2, C8) require trace cutting and manual placement per the BOM.

How does the optional C5 capacitor improve reliability on the MAX17554BEVKIT#?

The optional 22μF electrolytic capacitor (C5) on the MAX17554BEVKIT# dampens LC resonance between long input cables and ceramic input capacitors during hot-plug events. Its ESR suppresses voltage overshoot at the MAX17554B input, preventing potential overvoltage stress or false turn-on - a critical safeguard confirmed in the MAX17554BEVKIT# layout documentation.

Can the MAX17554BEVKIT# be used to evaluate different output voltages?

No - the MAX17554BEVKIT# is factory-configured for fixed 5V output using the internal feedback divider of the MAX17554B. Output voltage cannot be adjusted without modifying the feedback network, which is not supported by the default layout or BOM. For variable-output evaluation, refer to the MAX17554B datasheet and consider custom design.

What safety precautions apply when operating the MAX17554BEVKIT#?

Users must disable the DC power supply before making connections, avoid contact with live circuitry, and wait ≥5 minutes after disconnecting power to allow high-voltage capacitors to fully discharge. These precautions prevent electric shock and protect the MAX17554BEVKIT# from damage due to improper handling during hot-plug or fault recovery scenarios.
