Analog Devices Inc./Maxim Integrated MAX17570AEVKIT#

Overview

MAX17570AEVKIT# from Analog Devices is a fully assembled and tested evaluation kit designed to characterize the MAX17570A high-voltage synchronous step-down DC-DC converter, supporting 4.5V–60V input, delivering up to 300mA at fixed 3.3V output, operating in PWM mode across all loads, and featuring adjustable UVLO, open-drain RESET, and external clock synchronization capability.

For engineers reviewing the MAX17570AEVKIT# datasheet, MAX17570AEVKIT# pinout, MAX17570AEVKIT# application, or MAX17570AEVKIT# equivalent, this kit enables rapid validation of high-efficiency power conversion in industrial, automotive, and distributed power systems where input voltage transients, EMI compliance, and thermal robustness are critical design constraints.

Technical Context

The MAX17570AEVKIT# hosts a complete, electrically isolated reference design for the MAX17570A IC, including optimized PCB layout, CISPR32 Class B-compliant EMI filtering, and hot-plug-ready input staging with optional 10µF/100V electrolytic damping capacitors (C103). It implements resistor-programmable EN/UVLO via R101/R102 and supports external clock synchronization through the RT/SYNC pin and C109.

This kit demonstrates real-world implementation of key MAX17570A features: 400kHz default switching frequency (set by R103), overcurrent and thermal shutdown protection, and stable 3.3V regulation under load steps up to 300mA - all verified with pre-characterized ceramic output capacitance (22µF/10V X7R, C110) and input staging (1µF/100V X7R, C107).

FAQ

What is the primary function of the MAX17570AEVKIT#?

The MAX17570AEVKIT# is an evaluation kit that provides a fully assembled, tested, and EMI-optimized reference design for the MAX17570A synchronous step-down DC-DC converter. It enables engineers to validate 4.5V–60V input-to-3.3V/300mA output performance, assess thermal behavior, verify UVLO programming, and test external clock synchronization - all without custom PCB development. The MAX17570AEVKIT# includes documented jumper configurations, bill-of-materials, and schematic files to support rapid integration into system-level testing.

Does the MAX17570AEVKIT# support both MAX17570A and MAX17570D ICs?

No - the MAX17570AEVKIT# is specifically configured for the MAX17570A IC, which operates exclusively in PWM mode across all load conditions. It includes dedicated components such as R103 (9.76kΩ) for 400kHz switching and C109 for external clock synchronization - a feature not available on the MAX17570D. The MAX17570DEVKIT# is the separate evaluation kit for the MAX17570D, which uses PFM mode at light loads and lacks SYNC capability.

How is input undervoltage lockout (UVLO) configured on the MAX17570AEVKIT#?

On the MAX17570AEVKIT#, UVLO is resistor-programmable using the voltage divider formed by R101 (3.32MΩ) and R102 (1.24MΩ), setting a default turn-on threshold of ~4.5V when jumper JU101 is left open. Installing a shunt across pins 2–3 of JU101 disables the converter by grounding the EN/UVLO pin. The MAX17570AEVKIT# also supports external drive of the EN/UVLO pin with ≥1kΩ series resistance to suppress ringing - a configuration validated in the kit's layout and test procedures.

What EMI compliance level does the MAX17570AEVKIT# meet?

The MAX17570AEVKIT# meets CISPR32 Class B limits for both conducted and radiated emissions, verified per the official Analog Devices evaluation kit documentation. This compliance is achieved through its integrated EMI filter (including common-mode chokes and X/Y capacitors), optimized high-frequency layout with minimized loop areas, strategic placement of input/output capacitors (C107, C110), and shielding-aware routing - enabling direct use in pre-compliance testing for commercial and industrial end equipment.

Can the MAX17570AEVKIT# be used with long input cables or hot-plug sources?

Yes - the MAX17570AEVKIT# includes optional 10µF/100V aluminum electrolytic capacitors (C103) specifically placed to dampen input-voltage oscillations caused by cable inductance or precharged backplane sources. These components reduce peak voltage excursions during hot plug-in events and stabilize operation when powered from long cables, as confirmed in the kit's detailed description and typical operating characteristics data under transient conditions.
