Skyworks introduces digital isolators with integrated power
Skyworks has announced the Si86Px family of digital isolators with integrated power, a compact solution that combines digital isolation with an integrated isolated dc‑dc converter and matched miniature transformer. Designed for industrial and automotive electronics, the Si86Px simplifies isolated system design while reducing PCB area, BOM count, and overall design complexity.
The Si86Px addresses a critical challenge for system designers: generating high‑quality isolated power in applications where board space is limited or where no power source is readily available on the isolated side. By integrating signal and power isolation into a single package, the Si86Px can help reduce time to market while providing a well-regulated power source for sensitive components such as ADCs and sensors.
The Si86Px family integrates Skyworks’ digital isolator technology with an isolated dc‑dc converter capable of delivering up to 0.5 W of isolated power. This approach eliminates the need for bulky external transformers and power modules, enabling more compact and cost‑effective system designs.
Designed for harsh environments – operates over a wide –40°C to +125°C temperature range and provides 3.75 kVrms isolation, making it well suited for industrial automation, factory equipment, and automotive applications
Simplified system design – integrated power architecture and low‑EMI design help designers meet system‑level performance and compliance requirements with fewer external components
Significant tighter load regulation – delivers 0.1% typical load regulation, compared to 1% typical for comparable integrated power isolators, providing up to 10× better regulation for powering sensitive analog components
Higher data‑rate capability – supports up to 150 Mbps, exceeding devices rated at 100 Mbps or below for faster and more responsive system control
Robust data integrity – features 100 kV/µs common‑mode transient immunity (CMTI) for reliable operation in harsh electrical noise
