ADuM5000
Overview
The ADuM5000 is an isolated DC-to-DC converter based on Analog Devices isoPower technology, providing up to 500 mW of regulated, isolated power. It eliminates the need for a separate isolated DC-to-DC converter in low-power designs by integrating the transformer and control electronics into a 16-lead SOIC package. This device supports output voltages of 3.3V or 5V and provides 2.5 kV of isolation.
Why Choose This Part
The primary advantage is the high level of integration, which significantly reduces PCB footprint compared to discrete isolated transformer designs. It offers built-in thermal overload protection and operates across a wide temperature range of -40C to +105C, making it suitable for harsh industrial environments.
Applications
Key Specifications
Getting Started
To implement the ADuM5000, ensure adequate decoupling capacitors are placed close to the VDD1 and VISO pins to manage high-frequency switching noise. Engineers should follow the recommended PCB layout guidelines regarding creepage and clearance to maintain the 2.5 kV isolation rating. Evaluation can be performed using the ADuM5000EBZ evaluation board to test load regulation and efficiency.
