Overview

The RI-0505S is an isolated 2W DC/DC converter module designed to provide a regulated 5V output from a nominal 5V input. It features 1kVDC isolation in a compact 4-pin SIP package, making it an efficient solution for breaking ground loops and providing local voltage regulation in noise-sensitive circuits. The module achieves up to 83% efficiency and includes short-circuit protection for improved system reliability.

Why Choose This Part

This converter provides a high power density of 2W in a standard SIP4 footprint, saving significant board space compared to discrete isolated designs. Its 83% efficiency minimizes thermal management requirements, allowing for reliable operation from -40C to +85C.

Applications

Ground Loop Elimination
Ideal for isolating digital circuits from sensitive analog front-ends to prevent noise coupling and ground loops.
Industrial Interface Power
Providing isolated power to RS-485 or CAN bus transceivers to protect control logic from high-voltage transients.
Distributed Power Architectures
Local regulation and isolation for point-of-load applications in systems with 5V primary power rails.

Getting Started

To integrate this module, place a 4.7uF to 10uF low-ESR ceramic capacitor on the input and output rails to minimize ripple and noise. Ensure that the 4-pin SIP footprint follows the 2.54mm pitch standard for easy through-hole mounting. Since it is a self-contained module, no external inductors or feedback loops are required for standard operation.
