Reinforced Digital Isolators with Integrated DC-DC Converter
TI’s ISOW784x family of digital isolators integrates a DC-DC power converter that provides up to 650 mW of isolated power at high efficiency. The devices eliminate the need for a separate isolated power supply in space-constrained, isolated designs. The signal isolation channel has a logic input and output buffer, separated by a silicon dioxide (SiO2) insulation barrier, whereas, power isolation uses on-chip transformers separated by thin film polymer as insulating material.

Why use the ISOW784x isolators with integrated power?
- Integrated isolated power and data up to 100 Mbps, minimizing board space and cost for simplified system design.
- 80% higher efficiency than other integrated solutions, enabling higher power delivery and longer system lifetime.
- Lower radiated emissions than competitive integrated devices, improving system signal integrity and providing robust EMC to meet IEC 61000-4-x standards.
