Monolithic Power Systems Inc. EV02W0303A-3-Y-00A

Overview

EV02W0303A-3-Y-00A from Monolithic Power Systems is an evaluation board for the MID02W0303AGY-3R regulated, 3kVDC isolated DC/DC converter module, supporting 3.3V output at up to 75mA from a 3–3.6V input, in a compact 5.1cm × 5.1cm × 0.3cm two-layer PCB format. It demonstrates high-reliability isolated power delivery for space-constrained industrial and medical signal isolation applications.

For engineers reviewing the EV02W0303A-3-Y-00A datasheet, EV02W0303A-3-Y-00A pinout, EV02W0303A-3-Y-00A application, or EV02W0303A-3-Y-00A equivalent, this board enables rapid validation of the MID02W0303AGY-3R's line/load regulation, ripple performance, and thermal derating behavior under real-world load transients and input variation.

Technical Context

The EV02W0303A-3-Y-00A implements a complete test platform for the MID02W0303AGY-3R SOIC-16WB module, which integrates primary-side MOSFET, transformer, and optocoupler-based feedback in a single package. It supports 3kVDC reinforced isolation per UL60950-1 and IEC60664-1.

Board-level design includes dual-input/output decoupling (10μF + 0.1μF ceramic per rail), split ground planes (GND1/PGND1 and GND2/PGND2), and clearly labeled VIN/VOUT/GND terminals for direct connection to bench supplies and loads without modification.

FAQ

What is the primary purpose of the EV02W0303A-3-Y-00A?

This board is a dedicated evaluation platform for the MID02W0303AGY-3R isolated DC/DC converter module. It provides pre-layout, tested circuitry-including input/output filtering, ground separation, and terminal access-to validate electrical performance, thermal behavior, and system integration without custom PCB design.

Does the EV02W0303A-3-Y-00A require external components to operate?

No external components are required for basic operation. The board includes all necessary input/output capacitors (10μF + 0.1μF per rail), proper ground segmentation, and clearly marked VIN, VOUT, GND1, and GND2 terminals. Users only need a 3–3.6V DC supply and load.

Can the EV02W0303A-3-Y-00A be used for long-term deployment?

No-it is strictly an evaluation tool, not a production-grade module. Its layout and component selection prioritize testability and measurement access over extended reliability or environmental ruggedness. For production, the MID02W0303AGY-3R module must be integrated into a custom-designed PCB meeting safety spacing and thermal requirements.

What isolation standard does the underlying module meet?

The MID02W0303AGY-3R module on this board is rated for 3kVDC isolation and complies with reinforced insulation requirements per UL60950-1 and IEC60664-1. Test reports and certification documentation are provided separately by MPS and must be reviewed for end-equipment compliance.

How is thermal performance characterized on this board?

Thermal derating is documented across 0–75mA load and −25°C to +125°C ambient, showing linear current reduction above 75°C. The board uses 2-layer 1oz copper with no heatsinking-results reflect worst-case convection-only cooling, enabling conservative thermal margin estimation in target systems.

Are schematics and layout files available for this evaluation board?

Yes-full schematic (including SOIC-16WB pin mapping), BOM, and Gerber files are included in the official EV02W0303A-3-Y-00A Rev. 1.0 documentation from Monolithic Power Systems, available for download at MonolithicPower.com.
