Analog Devices Inc./Maxim Integrated MAX17555BEVKIT#

Overview

MAX17555BEVKIT# from Analog Devices is a fully assembled and tested evaluation kit for the MAX17555B synchronous step-down DC-DC converter, supporting 10V–60V input and delivering a regulated 5V/50mA output at up to 87.3% peak efficiency with fixed 70kHz switching. It implements programmable EN/UV and HYST thresholds, open-drain RESET monitoring, hiccup-mode overcurrent protection, and thermal shutdown - validated for CISPR32 Class B conducted/radiated emissions compliance.

For engineers reviewing the MAX17555BEVKIT# datasheet, MAX17555BEVKIT# pinout, MAX17555BEVKIT# application, or MAX17555BEVKIT# equivalent, this kit enables rapid validation of ultra-small high-voltage buck converter performance, input undervoltage hysteresis configuration, RESET assertion timing, hot-plug transient suppression via optional C5, and EMI filter integration per CISPR32 Class B requirements.

Technical Context

The MAX17555BEVKIT# is a hardware reference platform-not an IC-designed exclusively to evaluate the MAX17555B (4V–60V input, 50mA, 8-pin TDFN) synchronous buck regulator. Its PCB layout includes designated footprints for EMI filter components (L2 cut trace), a configurable resistor network (R1/R2/R3) for setting VIN turn-on/off thresholds, and a dedicated RESET test point tied to the IC's open-drain output.

It operates with internal loop compensation and 0.8ms typical soft-start, requires no external compensation, and supports verification of hiccup-mode response under overload/short-circuit and thermal shutdown behavior. The board integrates C5 (22μF electrolytic) specifically to dampen LC oscillations during hot-plug events with long input cables.

FAQ

What is the primary function of the MAX17555BEVKIT#?

The MAX17555BEVKIT# is a fully assembled evaluation kit designed solely to characterize and validate the electrical performance, protection features, and configuration flexibility of the MAX17555B synchronous step-down DC-DC converter. It is not a production-ready power module but a bench-level tool for verifying input UVLO hysteresis, RESET timing, efficiency curves, EMI filter integration, and thermal behavior under real operating conditions.

Does the MAX17555BEVKIT# require external components to operate?

No - the MAX17555BEVKIT# is fully assembled and tested with all critical components installed, including C1–C5, R1–R6, L1, and U1 (MAX17555BATA+). Only a 10V–60V DC power supply and a 5V load (up to 50mA) are required to operate the MAX17555BEVKIT#. Optional EMI filter parts (L2, C2, C8) are footprinted but not populated by default.

How is input undervoltage lockout configured on the MAX17555BEVKIT#?

The MAX17555BEVKIT# uses a three-resistor network (R1 = 3.32MΩ, R2 = 412kΩ, R3 = 2.4MΩ) connected between VIN, EN/UV, HYST, and GND to set turn-on at ≤13V and turn-off at ≤10V. This configuration matches the MAX17555B's internal comparator thresholds and is documented in the EV kit schematic and BOM - enabling direct validation of programmable UVLO hysteresis without modification.

What role does capacitor C5 play on the MAX17555BEVKIT# PCB?

C5 (22μF, 100V electrolytic) is an optional component on the MAX17555BEVKIT# that dampens voltage overshoot during hot-plug events when long input cables are used. Its ESR suppresses LC ringing caused by cable inductance interacting with input ceramic capacitors - a design-specific mitigation not required for short-cable lab use but critical for field-representative stress testing.

Is the MAX17555BEVKIT# compliant with electromagnetic interference standards?

Yes - the MAX17555BEVKIT# PCB layout and component selection meet CISPR32 Class B limits for both conducted and radiated emissions when the optional EMI filter (installed after cutting the L2 trace) is used. The board includes dedicated footprints and routing for filter inductors and capacitors, and its layout minimizes high-di/dt loop areas to inherently limit radiated noise from switching nodes.
