Monolithic Power Systems Inc. EVM3593-QY-00B

Overview

EVM3593-QY-00B from Monolithic Power Systems is an evaluation board for the MPM3593GQY 45V-input, 3A synchronous step-down module with I²C programmability, integrated OTP memory, and full protection (UVLO/OVP/OCP/OTP). It delivers 5V/3A output with <1% load regulation, supports 3.5–45V input, and enables voltage slew rate, switching frequency, and power-save mode configuration via I²C.

For engineers reviewing the EVM3593-QY-00B datasheet, EVM3593-QY-00B pinout, EVM3593-QY-00B application, or EVM3593-QY-00B equivalent, this board provides validated reference design, GUI-controlled parameter tuning, thermal performance validation, and EMC-compliant layout for industrial and automotive DC-DC subsystem development.

Technical Context

The EVM3593-QY-00B implements a complete functional demonstration of the MPM3593GQY QFN41 (6×8 mm) module, including its integrated high-side/low-side MOSFETs, bootstrap circuitry, and I²C-configurable control logic. It incorporates a 4.7 µH power inductor, 10 µF input/output ceramic capacitors, and discrete resistors for address selection and fault signaling.

Board-level features include dedicated test points for VIN, VOUT, SW, PG, FT, SCL, SDA, EN, and SYNC; a 4-pin header for I²C bus connection; and copper-pin headers for power and load interfacing. Conducted/radiated emission testing confirms compliance with CISPR 22 Class B limits using standard Pi-filter input conditioning.

FAQ

What software is required to configure the EVM3593-QY-00B?

The board requires the official MPM3593 EVKT User Guide and associated GUI software provided by MPS. This tool enables real-time register access, voltage/frequency/slew rate adjustment, and one-time programmable (OTP) memory writes via USB-connected I²C bus adapter. No third-party drivers or SDKs are needed beyond the MPS-supplied package.

Does the EVM3593-QY-00B support adjustable output voltages?

Yes - though shipped with 5 V output, the underlying MPM3593GQY supports programmable VOUT from 0.6 V to 12 V via I²C register writes. The evaluation board's feedback network is compatible with external resistor dividers, and the GUI allows full VOUT register configuration before writing to OTP memory.

Can the EVM3593-QY-00B be used for thermal testing under full load?

Yes - the board is designed for continuous 3 A operation at 5 V output with documented thermal performance. Test reports show junction temperature rise ≤25°C above ambient at 24 V input/3 A load with 200 LFM airflow, and thermal vias under the QFN41 package ensure reliable heat dissipation during sustained stress testing.

Is the I²C address configurable on this evaluation board?

Yes - the board includes resistor-based I²C address selection (R1–R5), allowing users to set one of eight possible addresses (0x60–0x67) by populating specific 100 kΩ resistors. This enables multiple EVMs or production modules to coexist on the same I²C bus without address conflict.

What safety certifications does the EVM3593-QY-00B hold?

The EVM3593-QY-00B itself is not a certified end-product and carries no UL, CE, or TÜV marks. However, it implements MPS-recommended layout practices and filtering that support compliance with CISPR 22 Class B emissions when integrated into certified systems. Safety isolation and creepage/clearance follow IPC-2221B guidelines for functional low-voltage DC-DC evaluation.

Are schematic and PCB layout files available for this evaluation board?

Yes - MPS provides full design resources including schematic (PDF), PCB layout (Gerber), BOM, and assembly drawings in the EVM3593-QY-00B User Guide Rev. 1.0. These files are intended for reference, reverse-engineering analysis, and derivative design - not for commercial redistribution or resale.
