Analog Devices Inc./Maxim Integrated MAX17553BEVKIT#

Overview

MAX17553BEVKIT# from Analog Devices is a fully assembled and tested evaluation kit designed to demonstrate the performance of the MAX17553B synchronous step-down DC-DC converter. It supports 6V–60V input, delivers 5V/50mA output, operates at 200kHz switching frequency, achieves 93.6% peak efficiency, and implements EN/UV and HYST threshold control with open-drain RESET monitoring.

For engineers reviewing the MAX17553BEVKIT# datasheet, MAX17553BEVKIT# setup procedure, MAX17553BEVKIT# input voltage range, or MAX17553BEVKIT# EMI filter configuration, this page provides verified operational context, BOM-level component validation, CISPR32 Class B compliance details, hot-plug protection implementation, and configurable EN/UV/HYST resistor network guidance.

Technical Context

The MAX17553BEVKIT# implements a fixed 200kHz buck converter topology using the MAX17553B IC in an 8-pin TDFN (2mm × 2mm) package. It integrates internal loop compensation, 3.2ms soft-start, hiccup-mode overcurrent protection, and thermal shutdown - all validated on a proven PCB layout with designated EMI filter footprints.

Input undervoltage enable (EN/UV) and hysteresis (HYST) are resistor-programmable via R1–R3 network; RESET asserts low when VOUT drops below 92% of 5V or EN/UV falls below threshold. Optional C5 (22μF electrolytic) dampens input LC oscillation during hot-plug with long cables.

FAQ

What is the primary function of the MAX17553BEVKIT#?

The MAX17553BEVKIT# is a ready-to-use evaluation kit that demonstrates the operation and performance of the MAX17553B synchronous step-down DC-DC converter. It enables engineers to validate input voltage range (6V–60V), output regulation (5V/50mA), efficiency (93.6%), protection features, and programmable EN/UV-HYST thresholds without custom PCB design. The MAX17553BEVKIT# includes all necessary passive components and a proven layout.

Does the MAX17553BEVKIT# support adjustable output voltage?

No - the MAX17553BEVKIT# is factory-configured for a fixed 5V output using onboard feedback resistors. While the underlying MAX17553B IC supports adjustable output via external resistor dividers, the MAX17553BEVKIT# itself is not shipped with user-modifiable output voltage circuitry. Output adjustment requires redesigning the feedback network per the MAX17553B datasheet, not supported out-of-box on the MAX17553BEVKIT#.

How is hot-plug protection implemented on the MAX17553BEVKIT#?

The MAX17553BEVKIT# implements hot-plug protection via optional electrolytic capacitor C5 (22μF, 100V), placed at the input to dampen LC oscillations caused by long input cables. Its ESR interacts with cable inductance to suppress voltage overshoot during connection. This design detail is explicitly documented in the MAX17553BEVKIT# layout notes and confirmed in the BOM and schematic.

What EMI standards does the MAX17553BEVKIT# meet?

The MAX17553BEVKIT# meets CISPR32 Class B limits for both conducted emissions (CE) and radiated emissions (RE) when used with the designated EMI filter components (L2, C2, C8) installed at their footprints and the L2 trace cut. The board layout is optimized to minimize switching node radiation, and compliance testing was performed per standard methodology as stated in the official documentation.

Can the MAX17553BEVKIT# be used to evaluate different switching frequencies?

Yes - the MAX17553BEVKIT# can be reconfigured for alternate switching frequencies by replacing inductor L1 and output capacitor C6 per the MAX17553B datasheet guidelines. Though shipped with 200kHz components (180μH L1, 10μF C6), the board's design accommodates other values to shift frequency while maintaining stability, provided internal compensation remains valid and layout parasitics are controlled.
