SOIC 8-Pin Package The TPS92023 is a high-performance resonantswitching LED driver controller. It is designed for use
in higher power LED lighting systems. The TPS92023
uses resonant switching in an LLC topology to
achieve a very high efficiency compared to traditional
half-bridge converters.
The programmable dead time enables zero-voltage
switching with minimum magnetizing current,
maximizing system efficiency across a variety of …
