Monolithic Power Systems Inc. EVM54504-BS-00A

Overview

EVM54504-BS-00A from Monolithic Power Systems is an evaluation board for the MPM54504 four-channel synchronous step-down power module, supporting 3–16V input and delivering 5A per channel at 3.3V, 2.5V, 1.5V, and 1.2V outputs with internal auto-compensation and COT control-designed for FPGA, ASIC, and multi-rail POL power validation.

For engineers reviewing the EVM54504-BS-00A datasheet, EVM54504-BS-00A pinout, EVM54504-BS-00A application, or EVM54504-BS-00A equivalent, this board enables rapid characterization of transient response, power sequencing (EN/PG), efficiency vs. load, and protection behavior across all four output rails under real-world thermal and layout conditions.

Technical Context

The EVM54504-BS-00A implements the MPM54504 FCMBGA power module with integrated inductors and monolithic FETs, enabling full four-channel operation without external compensation components. It supports independent enable (EN1–EN4) and power-good (PG1–PG4) signals for precise rail sequencing and system-level fault monitoring.

Tested at VIN = 12V and TA = 25°C, the board delivers ≥90% peak efficiency at 5A per channel (e.g., 92.5% at VOUT=1.2V/5A), <±0.5% load regulation, and <±0.3% line regulation-validated via oscilloscope waveforms for startup, shutdown, SCP recovery, and 1A/µs load transients with <50mV ripple.

FAQ

What input voltage range does the EVM54504-BS-00A support?

The board supports 3V to 16V DC input, matching the MPM54504's operational range. Tested performance data (efficiency, regulation, transient response) is provided at VIN = 5V and 12V per datasheet Section 6, with no derating required across the full range.

Can output voltages be reconfigured on this evaluation board?

Yes-output voltages are set by feedback resistors (R1, R6, R8, R12) per channel. The schematic (Figure 1) shows configurable FB networks; changing resistor values allows adjustment within the MPM54504's 0.6–5.5V range while maintaining stability due to internal auto-compensation.

Does the board include thermal management features?

Yes-the MPM54504GBS FCMBGA package is mounted directly to a 4-layer PCB with internal copper planes and thermal vias. The board achieves ≤65°C case temperature at full 5A/channel load (VIN=12V, TA=25°C), validated in thermal imaging tests documented in the EVB report.

How is power sequencing implemented?

Each channel has dedicated ENx and PGx pins routed to test points and headers. The Quick Start Guide (Section 3) confirms independent control; enabling channels sequentially (e.g., EN1→EN2→EN3→EN4) with 10ms delays meets typical FPGA I/O-to-core sequencing requirements.

Are external capacitors included for all four outputs?

Yes-the BOM lists eight 47µF ceramic capacitors (C6, C9, C14, C15, C23, C26, C29, C32) plus channel-specific bulk capacitance (e.g., C10 = 100µF for VOUT1), all placed per MPS layout guidelines to minimize ESR/ESL and ensure stability under fast transients.

Is the board RoHS-compliant and lead-free?

Yes-per the datasheet footer, all components including the MPM54504GBS module and passive parts meet RoHS Directive 2011/65/EU, are halogen-free, and carry MPS green status certification as confirmed on the official MPS Quality Assurance webpage.
