Monolithic Power Systems Inc. EVM54304-MN-01A

Overview

EVM54304-MN-01A from Monolithic Power Systems is an evaluation board for the MPM54304 four-channel DC/DC power module, supporting 4–16V input and delivering configurable outputs of 1V, 3.3V, 1.8V, and 1.5V with up to 3A/3A/2A/2A per channel. It integrates I²C programmability, MTP e-fuse configuration, and interleaved COT control-designed for FPGA and multi-rail MCU power validation.

For engineers reviewing the EVM54304-MN-01A datasheet, EVM54304-MN-01A pinout, EVM54304-MN-01A application, or EVM54304-MN-01A equivalent, this board enables rapid characterization of sequencing, efficiency, load transient response, and I²C register-level control of a monolithic quad-output PMIC in real-world multi-voltage rail systems.

Technical Context

The EVM54304-MN-01A implements the MPM54304GMN-0000 IC-a fully integrated LGA-packaged power module containing four synchronous buck converters, on-die inductors, and an I²C interface. Each channel uses constant-on-time (COT) control for sub-10µs load-step response and supports independent or paralleled operation (Ch1+Ch2 up to 6A; Ch3+Ch4 up to 4A).

Configuration is supported via I²C bus, external resistor dividers (0.55–5.4V range), or two-time programmable (MTP) e-fuse presets. Startup/shutdown sequencing, OVP/OCP thresholds, PWM/PFM mode selection, and switching frequency (default 800kHz) are all software-configurable through the GUI tool and register map.

FAQ

What is the primary function of the EVM54304-MN-01A?

This board is a dedicated evaluation platform for the MPM54304GMN-0000 quad-output power module. It provides full hardware access-including VIN, VOUTx, EN/SYNC, SCL/SDA, GPIO, and FB pins-to validate electrical performance, configure registers via I²C, and verify startup/shutdown sequences under real load conditions.

Does the board support parallel operation of output channels?

Yes-channels 1 and 2 can be paralleled for up to 6A total output, and channels 3 and 4 for up to 4A. The board's schematic and layout accommodate this via 0Ω jumpers (R2, R3, R4, R5) and shared feedback paths, as confirmed in the Bill of Materials and schematic diagrams.

How is output voltage configured on this evaluation board?

Voltage is set either via I²C register writes using the MPM54304 GUI software, by pre-programming the MTP e-fuse twice during manufacturing, or through external resistor dividers connected to FB1–FB4 pins. Default values (1V, 3.3V, 1.8V, 1.5V) are factory-preset on the MPM54304GMN-0000 IC.

What test data is included in the official documentation?

The Rev. 1.0 datasheet includes measured efficiency vs. load current (up to 3A per channel), line/load regulation curves, thermal power loss vs. temperature, startup/shutdown waveforms, and SCP entry/recovery behavior-all captured on this exact board at VIN=12V and specified output voltages.

Is external programming hardware required to use the I²C interface?

Yes-the board requires connection to an MPS I²C Start Kit (or compatible I²C master) via SCL, SDA, and GND pins. The GUI software-downloadable from the MPS website-then communicates with the MPM54304 to read/write registers, adjust parameters, and monitor telemetry in real time.
