Analog Devices Inc./Maxim Integrated MAX17504EVKITBE#

Overview

MAX17504EVKITBE# from Maxim Integrated is a fully assembled and tested evaluation kit designed to validate the MAX17504 high-voltage synchronous step-down DC-DC converter in 5V/3.5A output applications. It operates from 7.5V–60V input, delivers 5V at up to 3.5A load, features 500kHz switching frequency, adjustable UVLO and soft-start, and supports PWM/PFM/DCM mode selection via jumper configuration.

For engineers reviewing the MAX17504EVKITBE# datasheet, MAX17504EVKITBE# pinout, MAX17504EVKITBE# application, or MAX17504EVKITBE# equivalent, this kit provides a production-ready reference design for high-efficiency industrial power supplies, automotive subsystems, and distributed power architectures requiring CISPR22 Class B EMI compliance and robust thermal layout.

Technical Context

The MAX17504EVKITBE# implements the MAX17504 (TQFN20-EP, 5mm × 5mm) as a fixed 5V output buck converter with preset 500kHz operation, enabling optimal trade-offs between efficiency and passive component size. Input undervoltage lockout is resistor-programmable via R1/R2 on EN/UVLO, and mode selection (PWM/PFM/DCM) is controlled by JU2 shunt position.

It integrates open-drain RESET monitoring (95% VOUT rise, 92% fall thresholds), external clock synchronization via SYNC pad (JU3), and hot-plug protection using optional CIN4 (47µF/100V electrolytic). The PCB layout is optimized for conducted/radiated EMI suppression per CISPR22 Class B and includes designated footprints for EMI filter components.

FAQ

What is the primary function of the MAX17504EVKITBE#?

The MAX17504EVKITBE# is a fully assembled evaluation kit that validates the MAX17504 synchronous step-down DC-DC converter in 5V/3.5A applications. It provides a proven PCB layout, preconfigured jumpers for mode selection and UVLO, and built-in EMI optimization - enabling rapid functional verification and performance benchmarking without custom hardware design.

Does the MAX17504EVKITBE# support adjustable output voltage?

No, the MAX17504EVKITBE# is preset for a fixed 5V output. Output voltage is set by the FB resistor divider on the board and is not user-adjustable without modifying the schematic. For variable-output evaluation, engineers must use the MAX17504 data sheet to design a custom feedback network - the MAX17504EVKITBE# itself does not include potentiometer or DAC-based voltage tuning.

How is input undervoltage lockout configured on the MAX17504EVKITBE#?

On the MAX17504EVKITBE#, input undervoltage lockout is configured via jumper JU1 and external resistors R1 (3.32MΩ) and R2 (750kΩ). With JU1 open, VINU = 6.4V (default); installing R1/R2 allows setting custom turn-on thresholds using the formula VINU = 1.215 × (1 + R1/R2). JU1 pins 2–3 shorting disables the converter entirely.

Can the MAX17504EVKITBE# synchronize to an external clock?

Yes, the MAX17504EVKITBE# supports external clock synchronization via the SYNC pad and jumper JU3. When JU3 is set to pins 1–2 (open default), the SYNC pin accepts an external clock signal, forcing PWM-mode operation and eliminating frequency jitter. This capability enables deterministic timing in multi-rail systems and reduces beat-frequency EMI in synchronized power domains.

What EMI compliance level does the MAX17504EVKITBE# achieve out-of-the-box?

The MAX17504EVKITBE# achieves CISPR22 Class B conducted and radiated emissions limits without additional filtering components. Its optimized PCB stack-up, ground plane integrity, and layout of high-di/dt paths ensure compliance - verified in test reports showing peak emissions below Class B quasi-peak limits across 150kHz–30MHz (conducted) and 30MHz–1GHz (radiated).
