Monolithic Power Systems Inc. EVKT-MPM3593

Overview

EVKT-MPM3593 from Monolithic Power Systems is an evaluation kit designed to accelerate development and validation of the MPM3593GQY synchronous step-down power module - a digitally configurable 3A DC/DC converter with I²C interface, multipage one-time programmable (OTP) memory, 3.5V–45V input, 0.6V–12V output, and 500kHz default switching frequency. It enables rapid register-level configuration, OTP programming, and real-time performance monitoring for industrial and embedded power designs.

For engineers reviewing the EVKT-MPM3593 datasheet, EVKT-MPM3593 hardware setup, EVKT-MPM3593 software integration, or EVKT-MPM3593 ordering options, this page delivers verified specifications, system-level context, GUI workflow guidance, and supply support details required for lab evaluation and early-stage design validation.

Technical Context

The EVKT-MPM3593 integrates two core hardware components: the EVM3593-QY-00B evaluation board hosting the MPM3593GQY module, and the EVKT-USBI2C-02 USB-to-I²C interface dongle. It operates with Windows 7+ and requires MPS Virtual Bench Pro GUI software for register access, OTP write operations, and fault diagnostics.

Hardware interaction follows a strict sequence: VIN (3.5–45V) powers the board, VOUT delivers up to 3A at user-programmable voltage, and I²C communication enables read/write to volatile registers or permanent storage in OTP pages. Configuration persistence requires explicit OTP write at ≥12V input, followed by power cycle.

Key Specifications

Availability

EVKT-MPM3593 is available at Aetrix Electronics and suitable for power architecture validation, digital PMIC bring-up, and firmware-integrated power sequencing requiring stable component supply across prototyping, qualification, and pre-production phases.

Supply support for EVKT-MPM3593 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Monolithic Power Systems (MPS) is a fabless semiconductor company specializing in high-performance power management ICs, including DC/DC converters, LED drivers, and motor drivers, with global design and support infrastructure.

The EVKT-MPM3593 belongs to MPS's digital power evaluation platform family, engineered to reduce time-to-test for I²C/PMBus-configurable power modules used in space-constrained, thermally demanding applications such as networking equipment and industrial controllers.

FAQ

What software is required to operate the EVKT-MPM3593?

MPS Virtual Bench Pro GUI is mandatory. It is delivered preloaded on the included Tdrive-MPM3593 USB flash drive and supports Windows 7 or later. The tool provides full register access, OTP programming, real-time telemetry, and fault logging - no third-party drivers or SDKs are needed beyond the bundled USBXpress driver for EVKT-USBI2C-02.

How do I retain configuration settings after power cycling?

Register values are volatile and lost on power-down unless explicitly written to OTP memory. To persist settings, raise input voltage to ≥12V, click "Write to OTP" in Virtual Bench Pro, wait for confirmation, then power-cycle the board. OTP writes are irreversible and limited to one per page.

Can the EVKT-MPM3593 evaluate multiple MPM3593 modules simultaneously?

No - the kit supports only one MPM3593GQY module at a time on the EVM3593-QY-00B board. The included second module (MPM3593GQY-0001) serves as a spare or for parallel testing setups, but the GUI and hardware interface are single-device optimized.

What happens if the GUI fails to detect the MPM3593 on the board?

First verify USBXpress driver installation for EVKT-USBI2C-02 and confirm correct COM port assignment. Then manually initiate PMBus Tool → Scan in the GUI to identify the slave address (default 0x60), right-click "MPM3593", select "Change Chip Address", and enter the detected value. Physical reseating of ribbon and USB cables often resolves connection timeouts.

Is the EVKT-MPM3593 compatible with Linux or macOS?

No - MPS Virtual Bench Pro GUI is Windows-only (32/64-bit). No native Linux/macOS version exists, and compatibility via Wine or virtualization is unsupported and not validated by MPS. Evaluation on non-Windows platforms requires dual-boot or dedicated Windows hardware.

Does the kit include documentation for the MPM3593GQY IC itself?

Yes - the Tdrive-MPM3593 USB flash drive contains the MPM3593GQY datasheet, application notes, and reference schematics. The EVKT-MPM3593 User Guide (rev 1.1) focuses on kit operation, while device-level electrical specs, timing diagrams, and layout guidelines reside in the separate MPM3593GQY datasheet.
