Overview

The RO-0505S is a sub-miniature 1W unregulated DC/DC converter in a standard SIP4 package. It provides 1kVDC galvanic isolation between a 5V input and a 5V output, making it an efficient solution for breaking ground loops and isolating digital logic.

Why Choose This Part

This converter offers a high power density in a compact footprint, requiring no external components for operation. It features a wide operating temperature range of -40 Celsius to +85 Celsius without derating, ensuring reliability in varied thermal environments.

Applications

Ground Loop Elimination
Breaking ground paths between sensitive analog circuitry and noisy digital ground planes in mixed-signal systems.
Digital Logic Isolation
Providing isolated power to logic gates or small microcontrollers to prevent noise propagation across the PCB.
RS-232/RS-485 Node Power
Powering the isolated side of communication transceivers to ensure robust data transmission in industrial environments.
Sensor Interface Power
Isolating low-power sensors from the main system rail to protect against transients and common-mode noise.

Getting Started

When integrating this converter, ensure a minimum load of 10% is maintained to keep the output voltage within the specified tolerance. Place a low-ESR decoupling capacitor close to the input pins to minimize reflected ripple current and comply with EMI requirements.
