Analog Devices Inc./Maxim Integrated MAX17555AEVKIT#

Overview

MAX17555AEVKIT# from Analog Devices is a fully assembled and tested evaluation kit designed to demonstrate the performance of the MAX17555A - a 4V to 60V, 50mA synchronous step-down DC-DC converter in an 8-pin TDFN (2mm × 2mm) package. It operates from 7.5V–60V input, delivers 3.3V/50mA output, features 70kHz fixed-frequency operation, 87% peak efficiency, and supports EN/UV threshold and hysteresis configuration for industrial power supply validation.

For engineers reviewing the MAX17555AEVKIT# datasheet, MAX17555AEVKIT# pinout, MAX17555AEVKIT# application, or MAX17555AEVKIT# equivalent, this kit enables rapid functional verification of input undervoltage lockout, RESET monitoring, hiccup-mode protection, EMI filter integration, and hot-plug transient suppression using optional C5.

Technical Context

The MAX17555AEVKIT# implements a proven PCB layout optimized for the MAX17555A IC, supporting input voltage sequencing via resistor-programmable EN/UV and HYST pins, and providing a dedicated RESET output that asserts low when VOUT drops below 92% of 3.3V or EN/UV falls below threshold.

It integrates internal loop compensation, 0.8ms soft-start, bootstrap-based high-side gate drive, and built-in thermal shutdown. The board includes designated footprints for CISPR32 Class B-compliant conducted EMI filtering, with trace-cut provision at L2 for filter insertion.

FAQ

What does the MAX17555AEVKIT# evaluate?

The MAX17555AEVKIT# evaluates the MAX17555A - a 4V to 60V, 50mA synchronous step-down DC-DC converter. It provides a complete, tested platform to verify regulation accuracy, EN/UV hysteresis behavior, RESET timing, overload protection, and EMI performance. All key functions of the MAX17555A are accessible and measurable on the MAX17555AEVKIT# board.

Does the MAX17555AEVKIT# require external components to operate?

No - the MAX17555AEVKIT# is fully assembled and tested with all required components installed, including C1–C5, R1–R6, L1, and U1 (MAX17555AATA+). Only a 7.5V–60V DC power supply and optional load are needed for basic operation. Optional EMI filter parts (L2, C2, C8) may be added per the BOM if CISPR32 Class B compliance is required.

How is input undervoltage lockout configured on the MAX17555AEVKIT#?

The MAX17555AEVKIT# uses R1 (3.32MΩ), R2 (576kΩ), and R3 (2.4MΩ) to set EN/UV turn-on at 10.1V max and turn-off at 7.5V max. These resistors form a voltage divider network between VIN, EN/UV, HYST, and GND. Configuration follows the equations in the MAX17555A datasheet, and values are verified in the EV kit BOM on page 5 of the user guide.

What is the purpose of capacitor C5 on the MAX17555AEVKIT#?

C5 (22μF, 100V electrolytic) is an optional component on the MAX17555AEVKIT# that dampens input voltage overshoot during hot-plug events with long cables. Its ESR suppresses LC oscillations between cable inductance and input ceramic capacitors (C1, C4), preventing damage to the MAX17555A and improving system reliability in field-deployed setups.

Does the MAX17555AEVKIT# support different output voltages?

The MAX17555AEVKIT# is factory-configured for 3.3V output. To change output voltage, the feedback resistor network must be modified per the MAX17555A datasheet - the current board uses internal feedback; no external resistors are populated. Users must refer to the MAX17555A IC datasheet for reconfiguration guidance before altering the MAX17555AEVKIT# layout.
