HW-DC-DIP-3W-12S05
3 W isolated DC-DC converter module with 12 V input, 5 V single output and 1.5 kV isolation in a DIP package.
The HW-DC-DIP-3W-12S05 is a Hawun isolated DC-DC converter module that takes a nominal 12 volt input and produces a regulated 5 volt output at 3 watts, with 1.5 kilovolt isolation in an industry-standard DIP package. It provides board-level isolated power for industrial, telecom and instrument designs, where the isolation breaks ground loops and protects sensitive circuits from the noise and transients of the input rail. The module is compact and easy to place, and its standard pinout suits designs that use a family of converters across several rails. Because the converter is often the first stage of a sensitive circuit, its noise and its transient behaviour matter as much as its efficiency, and the input filter and the layout around it decide the result. The part is suited to powering interface circuits, isolated sensor front ends and small analog rails where a clean, isolated supply is required. Every device is factory-traceable and ships with an import declaration, a certificate of origin and RoHS documentation. BeiLuo holds this part in regional stock and our FAE team supports converter selection, input filtering and layout.
FAE Professional Review
This is the small isolated converter we recommend when a board needs a clean, isolated rail for an interface or a sensor front end. It is compact, uses a standard pinout, and its isolation breaks ground loops that would otherwise inject noise into a measurement. Keep the input capacitor close to the module and the output away from sensitive analog circuits, and confirm the input range covers the rail's variation with margin.

Frequently Asked Questions
What does the isolation protect?
The isolation separates the input and output grounds, which breaks ground loops and protects the output circuit from the noise and transients of the input rail.
It also supports safety isolation where required.
How do I keep the output clean?
Place the input capacitor close to the module, keep the input loop small, and keep the output away from sensitive analog circuits. A small output filter further reduces ripple.
Layout and filtering decide the noise.
