Analog Devices Inc./Maxim Integrated MAX17553CEVKIT#

Overview

The MAX17553CEVKIT# from Analog Devices is a fully assembled and tested evaluation kit designed to demonstrate the performance of the MAX17553C synchronous step-down DC-DC converter - a 4V to 60V input, 12V/50mA output, 400kHz-switching, 95% peak efficiency regulator in an 8-pin 2mm × 2mm TDFN package. It supports EN/UV and HYST threshold programming, open-drain RESET monitoring, hiccup-mode overcurrent protection, and CISPR32 Class B conducted/radiated emissions compliance.

For engineers reviewing the MAX17553CEVKIT# datasheet, MAX17553CEVKIT# pinout, MAX17553CEVKIT# application, or MAX17553CEVKIT# equivalent, this kit enables rapid validation of input undervoltage lockout behavior, output voltage regulation stability under 0–50mA load, thermal shutdown response, and EMI filter integration using designated footprints per the BOM.

Technical Context

The MAX17553CEVKIT# implements a fixed 12V output configuration with preinstalled components including COILCRAFT LPS4018-224MR (220µH inductor), TDK C2012X7R1E475K125AB (4.7µF output capacitor), and resistor network (R1=3.32MΩ, R2=287kΩ, R3=953kΩ) setting VIN(ON)=20V and VIN(OFF)=14V. It uses internal loop compensation and a 3.2ms soft-start to minimize inrush current.

This EV kit operates across 14V–60V input, delivers up to 50mA continuous output, and integrates dedicated PCB footprints for optional conducted EMI filter components (e.g., cut trace at L2). The RESET signal asserts low when VOUT drops below 92% of 12V or EN/UV falls below its threshold, with 30µs delay on power-up release.

FAQ

What does the MAX17553CEVKIT# evaluate?

The MAX17553CEVKIT# evaluates the MAX17553C - a 4V to 60V input, 12V/50mA synchronous step-down DC-DC converter. It provides a fully assembled, tested reference design with preconfigured EN/UV thresholds (20V ON / 14V OFF), 400kHz switching, and built-in RESET monitoring. The MAX17553CEVKIT# allows direct measurement of efficiency, transient response, protection behavior, and EMI filter integration without component substitution.

Does the MAX17553CEVKIT# support adjustable output voltage?

Yes - the MAX17553CEVKIT# can be reconfigured for adjustable output voltage (0.8V to 0.9×VIN) by modifying the FB resistive divider (R4 and R5). The default 12V output uses R4=118kΩ and R5=100kΩ. The MAX17553CEVKIT# schematic and layout accommodate this change without PCB modification, and the MAX17553C datasheet provides the exact calculation method for new resistor values.

How is input undervoltage lockout set on the MAX17553CEVKIT#?

The MAX17553CEVKIT# sets input EN/UV and hysteresis using a three-resistor network (R1=3.32MΩ, R2=287kΩ, R3=953kΩ) connected to IN, EN/UV, HYST, and GND. This configures turn-on at 20V and turn-off at 14V. The MAX17553CEVKIT# documentation includes the exact equations and Figure 2 schematic to recalculate R2/R3 for alternate thresholds while maintaining compatibility with the MAX17553C's internal reference.

What EMI compliance does the MAX17553CEVKIT# meet?

The MAX17553CEVKIT# meets CISPR32 Class B conducted and radiated emissions limits when used with the optional EMI filter components installed at designated footprints (with trace L2 cut). Its PCB layout minimizes switching node loop area and includes ground plane integrity per Analog Devices' proven power design practices - enabling reliable pre-compliance testing before final system integration.

Can the MAX17553CEVKIT# be used for thermal stress testing?

Yes - the MAX17553CEVKIT# incorporates thermal shutdown protection per the MAX17553C IC specification and includes a thermally optimized layout with exposed pad grounding. Users can apply sustained 50mA load at maximum input (60V) to verify thermal shutdown activation temperature and recovery behavior. The MAX17553CEVKIT#'s fully assembled construction ensures consistent thermal performance matching production-grade implementation.
