Regulates LED Current without Secondary Side Sensing
- Critical Conduction Mode (CCM) (with Zero current detection for valley switching)
- Adaptive ON-Time Control with Inherent PFC
- Programmable Switch Turn-On Delay
- Over Temperature Protection
- 120V applications
Off-Line Primary Side Sensing Controller with PFC Evaluation Module Board LED Lighting Application
The TPS92314A19120VEVM 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 120V applications. LED Lamps: A19 (E26,E27 and E14)family of general LED lighting PWM controllers contain control and drive circuitry required for off-line isolated or non-isolated LED lighting applications.
