IB0503S-W75R3 Description

Short technical summary and product information.

The IB0503S-W75R3 is an isolated DC-DC converter module manufactured by Mornsun America LLC. It provides a single 3.3V output at 200mA, delivering 660mW of output power. The converter operates from a nominal input voltage of 4.75V and achieves an efficiency of 68%. This isolated module is designed for commercial ITE applications and complies with CE and UKCA standards, referencing standard number 62368-1.

 

The module supports one output and is supplied in a 4-SIP through-hole package with dimensions of 11.6mm x 6.0mm x 10.2mm. Its operating temperature range is -40°C to 85°C with derating. The compact SIP form factor makes it suitable for space-constrained board-level power conversion.

 

As an isolated module, it provides galvanic isolation between input and output, which is beneficial for systems requiring noise isolation or separate grounds. The 68% efficiency is typical for a low-power isolated converter of this class. Designers should consider derating above specified temperatures when operating near the upper limit of the -40°C to 85°C range.

 

The through-hole mounting allows for reliable mechanical attachment in prototype and production environments. With its 4-pin SIP layout, the IB0503S-W75R3 integrates easily into standard PCB designs for distributed power architectures.
