PRODUCT FEATURES

Get a more robust & higher performing replacement to optocouplers
Get a more robust & higher performing replacement to optocouplers

The UCC23513 opto-emulated gate driver is a pin-to-pin replacement for traditional optocouplers, built to maximize performance and protection while extending system lifetime. This new gate driver utilizes capacitive isolation technology to improve protection, reliability and performance in motor drive, UPS and industrial power supply applications.

High-accuracy flyback with no optocoupler
High-accuracy flyback with no optocoupler

If you were outlining key features for the flyback of the future, you’d probably prioritize higher efficiency, lower component count, and smaller solution size. We have good news—add “better output accuracy” to that list and you’d have TI’s new LM5180 PSR DC/DC flyback converter.
