TPS92310 Off-Line Primary Side Sensing LED Driver with PFC

• Primary side regulation eliminates optocoupler, secondary error amplifier and associated passive components
• Select from two operating modes:
  • Adaptive COT provides inherent power factor correction with no external components
  • Peak current control provides low LED current ripple to minimize stroboscopic effects
• Critical-Conduction-Mode (CCM) with valley switching for low EMI
• Cycle-by-cycle current limit, over/under voltage protection and thermal shutdown
