Analog Devices Inc./Maxim Integrated MAX15258DL2EVKIT#

Overview

MAX15258DL2EVKIT# from Analog Devices is a fully assembled and tested evaluation kit designed to characterize the MAX15258 high-voltage multiphase inverting buck-boost controller. It supports single- to quad-phase configurations with discrete MOSFETs, operates from –36V to –60V input, delivers 24V–50V output, and integrates I²C-based programmability via a MAX32625PICO interface board for VREF, current limit, telemetry, and fault monitoring.

For engineers reviewing the MAX15258DL2EVKIT# datasheet, MAX15258DL2EVKIT# pinout, MAX15258DL2EVKIT# application, or MAX15258DL2EVKIT# equivalent, this kit enables rapid validation of high-efficiency, high-voltage DC-DC conversion in industrial power supplies, test equipment, and programmable lab sources where negative-input, positive-output regulation is required.

Technical Context

The MAX15258DL2EVKIT# implements a proven six-layer PCB design centered on the MAX15258ATX+ controller IC, two MAX15013CASA+ half-bridge drivers, and an onboard MAX17760ATC+ buck converter supplying 10V to the control circuitry. It uses banana jacks for safe high-voltage input (–36V to –60V) and output (24V to 50V) connections and includes test points for Bode analysis, phase current sensing, and voltage regulation verification.

Communication is handled by a soldered-on MAX32625PICO microcontroller board connected via headers J7/J13, enabling full I²C access to internal registers-including VREF_COMMAND (0–2.2V), OC_FAULT_LIMIT (20mV–100mV), VIN/VOUT readback, and status flags-through the downloadable MAX15258 GUI software.

FAQ

What is the primary function of the MAX15258DL2EVKIT#?

The MAX15258DL2EVKIT# is a fully assembled evaluation platform for the MAX15258 controller IC. It enables engineers to validate performance of high-voltage multiphase inverting buck-boost topologies, including input/output voltage regulation, phase current balancing, I²C programmability, and fault response-without requiring custom PCB design or layout effort. The MAX15258DL2EVKIT# includes all necessary power stages, drivers, and interface hardware.

Does the MAX15258DL2EVKIT# require external hardware to operate?

Yes. The MAX15258DL2EVKIT# requires a –36V to –60V DC power supply (e.g., 48V), a 0–16A load, and a MAX32625PICO board soldered onto headers J7 and J13 for I²C communication. The GUI software must be installed on a Windows PC, and the PICO board must be connected via USB to configure and monitor the MAX15258DL2EVKIT# in real time.

Can the MAX15258DL2EVKIT# be used for quad-phase operation?

Yes, but two MAX15258DL2EVKIT# units are required-one configured as primary controller and one as secondary-using jumpers J1, J2, J8–J11 to interconnect them. Each kit must have a unique I²C address (set via jumper J6), and the MAX15258 GUI supports coordinated control of both units for synchronized quad-phase operation.

How is output voltage adjusted on the MAX15258DL2EVKIT#?

Output voltage on the MAX15258DL2EVKIT# can be adjusted in two ways: (1) by modifying the external resistor divider between VOUT+ and OUTP pins, or (2) by applying an external 1V–2.2V reference to the REFIN test point (after removing R9). Alternatively, the internal VREF can be programmed digitally via the VREF_COMMAND register using the MAX15258 GUI-though this feature is active only on the primary controller in multiphase setups.

What safety and measurement features does the MAX15258DL2EVKIT# include?

The MAX15258DL2EVKIT# includes banana jacks rated for high-voltage operation, dedicated test points for VIN_P/VIN_N and VOUT_P/VOUT_N (enabling accurate efficiency measurements), BODE+/BODE– points for small-signal loop analysis, and EN/UVLO control via R19/R20 divider. It also integrates a MAX14933ASE+ I²C isolator to protect the host PC during communication, and TVS protection (SMAJ64A) on the input rail.
