Texas Instruments (TI) introduced a 450-V linear controller that simplifies current regulation of high-voltage LED strings. The TPS92410 controller integrates a multiplier and tunable phase dimmer detection, as well as analog dimming inputs and drive circuit protection functions to ease design of downlights, fixtures and lamps powered from an offline AC or conventional DC power source.  For more information, samples and evaluation modules, visit www.ti.com/tps92410-pr.
