Overview

The RFMM-0505S is a 1W isolated DC/DC converter designed to provide a regulated 5V output from a 5V input. Housed in a standard SIP7 package, it offers 4kVDC isolation, making it suitable for separating power rails in cost-sensitive commercial applications.

Why Choose This Part

This module features an industry-standard SIP7 footprint and a high 4kVDC isolation rating for enhanced safety and signal integrity. It provides a cost-effective solution with 80% efficiency and includes short-circuit protection for improved system reliability.

Applications

Ground Loop Elimination
Provides galvanic isolation to prevent ground loops in sensitive analog or digital communication circuits.
Digital Interface Power
Ideally suited for powering isolated logic level shifters or RS-485/RS-232 transceivers.
Industrial Instrumentation
Provides isolated 5V rails for sensors and low-power measurement circuits to improve noise immunity.
