Overview

The TEA 1-0505HI is an isolated 1W DC/DC converter module designed for cost-effective power distribution in commercial and industrial applications. It converts a nominal 5V DC input to a regulated 5V DC output with a maximum current of 200mA. This module features high isolation of 4 kVDC, making it suitable for protecting sensitive low-power circuitry from high-voltage noise or potential ground loops.

Why Choose This Part

The module offers a very high 4,000 VDC isolation rating in a compact SIP-7 package, optimizing board space while ensuring safety. With an efficiency of 78% and an operating temperature range of -40C to +85C, it provides reliable performance in standard industrial environments without requiring extensive cooling.

Applications

Ground Loop Elimination
Used to break ground loops in sensitive analog signal chains or communication interfaces.
Digital Interface Isolation
Provides isolated power for logic-level shifters or optocouplers in industrial control systems.
Distributed Power Architectures
Acts as a local point-of-load regulator for sub-circuits requiring a clean 5V rail separate from the main system bus.

Getting Started

To implement this converter, provide a stable 4.5V to 5.5V input across the specified pins and place ceramic decoupling capacitors close to the input and output pins to minimize switching noise. Ensure the PCB layout maintains the required creepage and clearance distances to preserve the 4 kV isolation integrity.
