Monolithic Power Systems Inc. EV06W0503A-3-Y-00A

Overview

EV06W0503A-3-Y-00A from Monolithic Power Systems is an evaluation board for the MID06W0503AGY-3S-Z semi-regulated, isolated DC/DC converter module, delivering 3.3 V at up to 0.18 A from a 4.5–5.5 V input, with 3 kVDC isolation and 0.6 W output power in a compact 5.1 cm × 5.1 cm × 0.3 cm two-layer PCB format.

For engineers reviewing the EV06W0503A-3-Y-00A datasheet, EV06W0503A-3-Y-00A pinout, EV06W0503A-3-Y-00A application, or EV06W0503A-3-Y-00A equivalent, this board enables rapid validation of isolated 3.3 V supply generation in space-constrained industrial and embedded systems requiring reinforced insulation and low-noise operation.

Technical Context

The EV06W0503A-3-Y-00A implements a fixed-output, transformer-isolated flyback topology using the integrated MID06W0503AGY-3S-Z module, which embeds power MOSFET, transformer, and feedback circuitry in a single SOIC-16 WB package. It operates without external compensation components and supports primary-side regulation only.

Input-to-output isolation is rated at 3 kVDC (1 min, reinforced), with line regulation ±1.5% over 4.5–5.5 V input and load regulation ±2% across 0–180 mA output current at 25°C. The board includes input/output ceramic filtering (10 µF + 0.1 µF per rail) and dedicated ground separation (GND1/PGND1 and GND2/PGND2).

FAQ

What is the primary function of the EV06W0503A-3-Y-00A?

This evaluation board demonstrates the MID06W0503AGY-3S-Z isolated DC/DC converter module. Its sole purpose is to provide a ready-to-use platform for validating 3.3 V output, 3 kVDC isolation, and load behavior under real-world conditions-no firmware, configuration, or programming is involved.

Can the EV06W0503A-3-Y-00A be used in production systems?

No-it is strictly an evaluation tool. The board lacks conformal coating, long-term reliability qualification, and production-grade layout controls. For deployment, engineers must integrate the MID06W0503AGY-3S-Z module into their own PCB with appropriate creepage/clearance, thermal design, and safety certification.

Does the board support adjustable output voltage?

No. The MID06W0503AGY-3S-Z module is factory-trimmed for fixed 3.3 V output. There are no external resistors, pins, or configuration options to modify the output voltage on this evaluation board.

What are the required external connections for operation?

Only four terminals: VIN (+), GND1 (−) for input; VOUT (+), GND2 (−) for output. No enable, sync, or trim signals are present. Input must be within 4.5–5.5 V; output delivers 3.3 V automatically upon power-up.

How is isolation verified on this board?

Isolation is implemented via the internal transformer and reinforced insulation structure of the MID06W0503AGY-3S-Z module. The board maintains ≥8 mm creepage and clearance between primary (GND1) and secondary (GND2) sides, validated per IEC 62368-1 Annex Q and UL 62368-1 §5.5.2.

Are input/output capacitors included on the board?

Yes: two 10 µF X5R 0805 ceramics (C1A/C2A) and two 0.1 µF X7R 0402 ceramics (C1B/C2B) are placed adjacent to VIN and VOUT pins. These match the recommended values in the MID06W0503A datasheet for stable operation and ripple suppression.
