The TPS92020 is a high-performance resonant switching LED driver controller. It is designed for use in higher power LED lighting systems. The TPS92020 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 applications.
