TI's High Bay LED Lighting Solution

TI and National's winning combo features the UCC28810 LED Driver and Evaluation Module, the TPS92020 LED Controller, and the LM3409HV PFET Buck Controller

TPS92020 High Performance resonant switching LED driver controllerTexas Instruments' UCC28810 is a general lighting power controller for low to medium power lumens applications requiring power factor correction and EMC compliance. It is designed for controlling a flyback, buck, or boost converter operating in critical conduction mode. The UCC28810EVM-003 is a 110 W offline AC-to-DC LED current driver with power factor correction. This design utilizes a three stage approach with a universal input boost PFC stage, a low-side buck stage providing a controlled current source and a half-bridge DC transformer stage to provide isolation to four LED strings.

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.

National Semiconductor's LM3409HV is a P-channel MosFET (PFET) controller for step-down (buck) current regulators. It offers wide input voltage range, high-side differential current sense with low adjustable threshold voltage, fast output enable/disable function and a thermally enhanced eMSOP-10 package. These features combine to make the LM3409HV ideal for use as a constant current source for driving LEDs where forward currents up to 5 A are easily achievable.
