TPS92310-23FB/NOPB, Evaluation Board using TPS92310 single-stage AC/DC controller dedicated for LED Lighting applications. The controller uses a primary-side current sense configuration to control the LED current at secondly side. The system works in Critical Conduction Mode (CRM) with flyback topology and it employs a constant on time modulation scheme. Inherently, systems with this configuration can achieve greater than 0.90 Power Factor (PF) easily
