Reference Designs

This reference design provides a high-brightness LED driver based on the TPS92310 configured as a power factor corrected flyback regulator that is triac dimmable. It is designed to operate with an input voltage in the range of 90VAC to 135VAC with a 120VAC nominal input voltage. This design is set up for a default output current of 340mA with an output voltage range of 21V to 27V or approximately 6 to 8 LEDs depending on the forward voltage of each.
