Overview

The ROE-0505S is an unregulated 1W isolated DC/DC converter designed to provide a 5V output from a 5V input. It features 1kV DC isolation in a compact SIP4 package, making it an efficient solution for breaking ground loops and isolating digital noise from sensitive analog circuits.

Why Choose This Part

This module offers a high power density in a small 11.5mm x 6mm footprint with a wide operating temperature range of -40C to 85C. It provides a cost-effective alternative to larger discrete isolation solutions while maintaining an industry-standard SIP4 pinout.

Applications

Ground Loop Elimination
Used to isolate signal paths between different subsystems to prevent noise caused by potential differences in ground planes.
Digital Circuit Isolation
Separates noisy digital logic power rails from clean analog supply rails in mixed-signal environments.
Point-of-Load Regulation
Provides a localized 5V supply for sensors or communication interfaces requiring basic galvanic isolation.

Getting Started

To use the ROE-0505S, ensure a 4.5V to 5.5V input source is connected to pins 1 and 2, and the 5V output is taken from pins 3 and 4. Add a 10uF ceramic capacitor at the input and output to minimize ripple, and ensure the 200mA maximum load is not exceeded.
