B0505LS-1WR3 Description

Short technical summary and product information.

The Mornsun B0505LS-1WR3 is an isolated DC-DC converter module designed for commercial ITE applications. It provides a single regulated 5V output at up to 200mA, delivering 1W of power. The module operates from a minimum input voltage of 4.5V and achieves a typical efficiency of 82%.

 

This converter is housed in a 7-SIP through-hole package with 4 leads, measuring 19.7mm x 6.0mm x 10.2mm. It operates over a wide temperature range of -40°C to 105°C, making it suitable for demanding environments. The module carries safety approvals from CB, CE, and cURus.

 

Designed for board-mount applications, the isolated topology provides galvanic isolation between input and output, enhancing system reliability. The compact SIP package saves space on the PCB while maintaining high power density. With its 1W rating and 5V output, this converter is well-suited for powering low-power digital circuits, sensors, and isolated interface circuits.
