RFM-0505S
Overview
The RFM-0505S is a compact, cost-effective 1W DC-DC converter designed for board-level power isolation. It provides a fixed 5V output from a 5V input with 1kVDC isolation, making it ideal for breaking ground loops or providing basic isolation in digital circuits. This unregulated module features an industry-standard SIP4 pinout and is certified to UL60950-1 and EN55032 standards.
Why Choose This Part
The RFM-0505S offers a high efficiency range of 79 to 84 percent in a very small 11.5mm x 6.0mm footprint. Its industry-standard SIP4 package allows for easy drop-in integration into existing designs without requiring complex PCB layouts. It provides a reliable 1kVDC isolation barrier while maintaining low cost for high-volume commercial applications.
Applications
Key Specifications
Getting Started
When integrating the RFM-0505S, ensure your input voltage stays within the 4.5V to 5.5V range as the device is unregulated. Engineers should place a 1uF to 10uF ceramic capacitor on the input and output pins to minimize ripple, as per typical application notes. Since this is a through-hole SIP4 module, it is easily evaluated on a standard breadboard or prototyping board before final PCB layout.
