This reference design uses TPS92410 and TPS92411 with 50-W output power for area lighting with all components on a single printed-circuit board (PCB). This design uses four TPS92411 stages allowing 16 different switch states during the rising and falling rectified-AC waveform, which optimizes the current-regulating MOSFET headroom. TPS92410 allows monotonic analog dimming down to 3% before shutting off the current regulator. Electromagnetic interference (EMI) filtering without magnetics has been included and designed to meet FCC Title 47 Part 15 Class-B conduction requirements.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
