Description

The TIDA-01399 TI Design showcases the 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. The 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.

Features
  • Non-Isolated 120-V AC Offline LED Driver With No Magnetics
  • Efficiency: 86.5%, Power Factor: 0.97, THD: 10.5%
  • FCC Title 47 Part 15 Class-B Tested EMI
  • Current Regulator for Power Factor Correction With Multiplier for Line Regulation
  • Allows Simple NTC Thermal Foldback
  • Monotonic Analog Dimming to 3% With Shutdown; Deeper Dimming Using TSNS Input
