Overview

The TEA 1-0505 is a compact 1 Watt isolated DC/DC converter designed to provide a regulated 5V output from a 4.5V to 5.5V input range. Housed in a standard 4-pin SIP package, it offers 1500 VDC I/O isolation, making it suitable for breaking ground loops and isolating noise in sensitive digital circuits.

Why Choose This Part

The SIP-4 package offers a very small footprint of 11.7mm x 6.0mm, saving significant board space in high-density designs. With 78% efficiency and a wide operating temperature range of -40 to +85 degrees Celsius, it provides reliable performance in industrial and commercial environments without requiring complex thermal management.

Applications

Ground Loop Elimination
Provides 1.5 kV isolation to prevent noise-inducing ground loops in communication and instrumentation circuits.
Digital Logic Isolation
Used to isolate sensitive microcontroller logic from noisy peripheral components or power rails.
Distributed Power Architectures
Efficiently converts 5V bus voltages into isolated 5V rails for small, local loads up to 200 mA.

Getting Started

As an unregulated module, ensure your input voltage stays within the 4.5V to 5.5V range for stable operation. For improved performance, place a 10uF low-ESR ceramic capacitor close to both the input and output pins to minimize ripple and noise. This component is a through-hole SIP-4 module that can be hand-soldered or wave-soldered directly to the PCB.
