Integrated power controller for LED lighting
Jun 06, 2022
ST has launched a digital power controller with distortion mitigation suitable for LED-lighting applications. The STNRG012 contains a multimode power-factor correction (PFC) controller, resonant half-bridge controller, and 800V startup circuit, managed by a digital engine. The PFC controller changes dynamically between transition-mode, discontinuous-current mode (DCM), and valley skipping for optimum efficiency.
