Analog Devices Inc./Maxim Integrated MAX17554CEVKIT#

Overview

MAX17554CEVKIT# from Analog Devices is a fully assembled and tested evaluation kit designed to demonstrate the performance of the MAX17554C, a 10V–60V input, 2.5V/50mA synchronous step-down DC-DC converter in an 8-pin TDFN (2mm × 2mm) package. It operates at a fixed 70kHz switching frequency, delivers up to 82% peak efficiency, and includes built-in hiccup-mode overcurrent and thermal shutdown protection.

For engineers reviewing the MAX17554CEVKIT# datasheet, MAX17554CEVKIT# setup, MAX17554CEVKIT# application, or MAX17554CEVKIT# configuration for high-voltage industrial power conversion validation, this EV kit provides proven PCB layout, EMI filter footprints per CISPR32 Class B compliance, and configurable output voltage via FB/VO resistive divider.

Technical Context

The MAX17554CEVKIT# implements a complete reference design for the MAX17554C IC, featuring fixed 70kHz operation, internal loop compensation, and 0.8ms typical soft-start. Input voltage turn-on is fixed at ≤42.5V and turn-off at ≤10V, enabling reliable high-input-voltage sequencing.

It supports conducted EMI filtering via designated footprints (e.g., C5 electrolytic capacitor location and L2 trace cut), and integrates a proven layout optimized for radiated emissions control per CISPR32 Class B. The board delivers stable 2.5V output across 10V–60V input and 0–50mA load, with validated thermal and overload protection behavior.

FAQ

What is the primary function of the MAX17554CEVKIT#?

The MAX17554CEVKIT# is a fully assembled evaluation kit used to validate the electrical performance, protection features, and EMI behavior of the MAX17554C synchronous step-down DC-DC converter. It provides immediate access to 2.5V/50mA output from 10V–60V input, with pre-verified layout and test points for bench characterization of the MAX17554C.

Does the MAX17554CEVKIT# support adjustable output voltage?

Yes - the MAX17554CEVKIT# supports output voltage adjustment from 0.8V to 0.9×VIN using an external resistive feedback divider connected to the FB/VO pin. The default configuration delivers 2.5V, but R6 (107kΩ) and R7 (49.9kΩ) can be replaced per the equation RU = RB × (VOUT/0.8 − 1) to reconfigure the MAX17554CEVKIT# for alternate output voltages.

How does the MAX17554CEVKIT# assist with EMI compliance testing?

The MAX17554CEVKIT# includes designated footprints for conducted EMI filter components (e.g., C5 and L2 cut-trace location) aligned with CISPR32 Class B requirements. Installing these components - such as the 22μF electrolytic capacitor (C5) - dampens input cable resonance and reduces high-frequency noise injection, allowing engineers to verify EMI mitigation strategies directly on the MAX17554CEVKIT#.

What protection features of the MAX17554C can be tested using the MAX17554CEVKIT#?

The MAX17554CEVKIT# enables direct validation of the MAX17554C's hiccup-mode overcurrent protection and thermal shutdown. By applying short-circuit or overload conditions at the VOUT pad, users observe automatic current limiting and recovery cycles; elevated temperature triggers shutdown, confirmed via thermal imaging or output dropout - all observable without modification to the MAX17554CEVKIT#.

Is the MAX17554CEVKIT# compatible with hot-plug input sources and long cables?

Yes - the MAX17554CEVKIT# PCB layout includes provision for C5 (22μF electrolytic capacitor), which limits input voltage overshoot during hot-plug events with long input cables. Its ESR damps LC oscillations between cable inductance and input ceramic capacitors, preventing damaging voltage spikes at the MAX17554C input - a key capability validated on the MAX17554CEVKIT#.
