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.

Texas Instruments offers a variety of options of capacitive based galvanic isolation. Take the challenge and compare optocouplers vs. capacitive based digital isolation products and you'll see TI offers higher reliability with improved performance all while covering isolation ratings from basic up to reinforced isolation. Our digital isolators come in a number of channel counts & orientations, fail safe outputs, and packaging options to suit any design. No matter if you call it "isolater" or "isolator" our digital isolators are certified by numerous worldwide entities, keeping your design up to code. In addition to our standard digital isolators we also offer isolated signal chain options such as Isolated CAN BusRS485Gate Drivers, LVDS and I2C.
