Off-Line Primary Side Sensing Controller with PFC Evaluation Module Board LED Lighting Application
The TPS92314 family of general LED lighting PWM controllers contain control and drive circuitry required for off-line isolated or non-isolated LED lighting applications. The TPS92314A19230VEVM evaluation module uses the TPS92314 as an isolated PFC flyback controller; more specifically it is an isolated primary-side controlled critical conduction mode PFC flyback. The controller operates in critical conduction valley switching, with minimal external parts count for 230V applications
