Analog Devices Inc./Maxim Integrated MAX25660EVKIT#

Overview

MAX25660EVKIT# from Analog Devices is a fully assembled and tested evaluation board designed to simplify characterization and functional validation of the MAX25660 400kHz/2.1MHz, 36V automotive-grade buck-boost DC-DC converter. It supports 4.5V–36V input, delivers 7V at up to 5A, and includes PGOOD monitoring, current-limit/hiccup protection, and output enable control.

For engineers reviewing the MAX25660EVKIT# datasheet, MAX25660EVKIT# pinout, MAX25660EVKIT# application, or MAX25660EVKIT# equivalent, this kit enables rapid power stage validation, frequency option evaluation (400kHz vs. 2.1MHz), thermal testing under load, and integration with LED driver reference designs such as MAX25630/MAX25631.

Technical Context

The MAX25660EVKIT# implements the complete power train of the MAX25660 IC-including integrated high-side and low-side MOSFETs-and supports seamless buck-to-boost transition across input voltages from 4.5V to 36V. It features configurable switching frequency via external resistor selection and provides access to critical nodes including SUP, OUT, PGOOD, EN, and VLED interface points.

Designed for automotive applications, all components on the board are AEC-Q200 qualified. The EV kit allows direct substitution of frequency-setting components to evaluate both 400kHz and 2.1MHz operation modes without PCB redesign, and supports connection to external LED current sinks via the VLED node.

FAQ

What is the primary function of the MAX25660EVKIT#?

The MAX25660EVKIT# is an evaluation board that enables functional testing and performance characterization of the MAX25660 buck-boost converter IC. It provides immediate access to input/output power nodes, control signals (EN, PGOOD), and configuration options for both 400kHz and 2.1MHz operation-without requiring custom PCB design. Engineers use the MAX25660EVKIT# to verify voltage regulation, transient response, thermal behavior, and compatibility with downstream devices like the MAX25630.

Can the MAX25660EVKIT# operate at both 400kHz and 2.1MHz?

Yes, the MAX25660EVKIT# ships with the 400kHz configuration installed by default, but it supports 2.1MHz operation through replacement of specific frequency-setting resistors and compensation components. The User Guide documents exact part numbers and placement locations required for reconfiguration. This dual-frequency capability allows engineers using the MAX25660EVKIT# to assess EMI filtering trade-offs and layout sensitivity across both switching regimes.

Does the MAX25660EVKIT# include automotive-qualified components?

Yes, all passive and active components on the MAX25660EVKIT# are automotive grade and AEC-Q200 qualified. This includes the inductor, capacitors, and feedback resistors-ensuring the board reflects real-world reliability expectations for automotive lighting and body control module applications. The MAX25660EVKIT# thus provides a production-representative test environment for the MAX25660 IC.

How is the MAX25660EVKIT# powered and loaded during evaluation?

The MAX25660EVKIT# accepts 4.5V–36V DC input via SUP/GND1 or SUP/GND3 terminals, with optional filtering via SUP_Filter. Load can be applied between OUT and GND2/GND4 using either a 35W-rated resistive load or an electronic load set to sink up to 5A. For LED applications, the MAX25660EVKIT# output connects directly to the VLED pin of compatible drivers such as the MAX25630, enabling end-to-end lighting subsystem validation.

Is the MAX25660EVKIT# compatible with other Analog Devices LED driver evaluation kits?

Yes, the MAX25660EVKIT# is explicitly designed to interoperate with the MAX25630 and MAX25631 evaluation kits. Its 7V output and VLED interface node align with the input requirements of those LED current sink ICs. The User Guide provides step-by-step instructions for cascading the MAX25660EVKIT# output into the MAX25630/MAX25631 EV kit power path-enabling full-system validation of automotive LED headlight or DRL architectures using the MAX25660EVKIT# as the front-end power stage.
