Texas 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.

Texas Instruments 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.
