Overview

The ROE-3.305S is an isolated 1W DC/DC converter module designed to provide a regulated 5V output from a 3.3V nominal input range (2.97V to 3.63V). This SIP4 package module provides 1kV DC isolation, making it suitable for breaking ground loops and reducing noise in digital-to-analog circuit interfaces. It operates efficiently over a wide temperature range from -40 degrees Celsius to 85 degrees Celsius.

Why Choose This Part

The ROE-3.305S offers a compact SIP4 footprint (11.5mm x 6mm) that saves significant board space compared to discrete isolated designs. It provides a fixed 5V output with 200mA maximum current, ensuring reliable operation without the need for external heatsinking in standard operating temperatures.

Applications

Digital Logic Level Shifting
Converting 3.3V logic supply rails to 5V for powering legacy sensors or peripherals in industrial environments.
Ground Loop Elimination
Providing 1kV isolation between input and output to prevent noise coupling in sensitive measurement circuits.
Point-of-Load Regulation
Localized power conversion for ITE and commercial equipment requiring small footprint 5V rails up to 200mA.

Getting Started

To use this module, connect the input pins to a stable 3.3V source with a minimum 4.7uF ceramic capacitor for decoupling. Ensure the PCB layout maintains the isolation creepage distance between the input and output pins. No external controllers or software are required for operation as it is a self-contained power module.
