Monolithic Power Systems Inc. EV02W0303A-2-Y-00B

Overview

EV02W0303A-2-Y-00B from Monolithic Power Systems is an evaluation board for the MID02W0303AGY-2R regulated, 1.5kVDC isolated DC/DC converter module, supporting 3.3V output at up to 75mA from a 3V–3.6V input, in a compact 5.1cm × 5.1cm × 0.3cm two-layer PCB format.

For engineers reviewing the EV02W0303A-2-Y-00B datasheet, EV02W0303A-2-Y-00B pinout, EV02W0303A-2-Y-00B application, or EV02W0303A-2-Y-00B equivalent, this board enables rapid validation of isolated power delivery in space-constrained, low-noise, and safety-isolated designs such as medical sensors and industrial I/O modules.

Technical Context

The EV02W0303A-2-Y-00B implements a fully integrated isolated DC/DC conversion path using the MID02W0303AGY-2R SOIC-16 WB module, which embeds power MOSFET, transformer, and feedback circuitry. Input-to-output isolation is rated at 1.5kVDC, with reinforced creepage/clearance design verified on the board layout.

It supports fixed 3.3V output regulation across 3V–3.6V input and 0–75mA load, with line regulation ≤±0.5% and load regulation ≤±1% under specified test conditions. Input and output filtering uses parallel 0.1µF + 10µF ceramic capacitors (X5R/X7R, 0402/0802).

FAQ

What is the primary purpose of the EV02W0303A-2-Y-00B?

This evaluation board is designed exclusively to demonstrate and validate the electrical performance, thermal behavior, and layout implementation of the MID02W0303AGY-2R isolated DC/DC converter module. It is not intended for end-product integration but for engineering verification prior to custom PCB design.

Can the EV02W0303A-2-Y-00B operate outside the 3V–3.6V input range?

No - the board is optimized for and validated only within the 3.0V to 3.6V input range, as defined by the MID02W0303AGY-2R's operational specification. Operation outside this range may cause undervoltage lockout, regulation failure, or permanent damage to the module.

Does the board include short-circuit protection?

Yes - the underlying MID02W0303AGY-2R module features internal short-circuit protection, and test waveforms in the reference document confirm automatic recovery after SCP event detection, with no external components required.

What is the creepage and clearance distance achieved on this board?

The board layout maintains ≥4.5 mm creepage and ≥3.2 mm clearance between primary (GND1/VIN) and secondary (GND2/VOUT) sides, satisfying reinforced insulation requirements for 1.5 kVDC working voltage per IPC-2221B guidelines.

Are input and output capacitors populated on the board?

Yes - the board ships with all four recommended input/output capacitors installed: two 10 µF X5R 0805 (C1A, C2A) and two 0.1 µF X7R 0402 (C1B, C2B), matching the BOM and schematic in the official revision 1.0 documentation.

Can this board be used to evaluate other MID02W variants?

No - the EV02W0303A-2-Y-00B is specifically laid out for the MID02W0303AGY-2R variant (3.3V output). Pinout, feedback network, and capacitor values are not compatible with other output voltages (e.g., 5V or 12V) in the same family.
