Abstract

An integrated ballast controller fabricated in a 0.8 mum CMOS process is presented that includes digital phase control, current regulation and soft-start ignition. The primarily digital approach provides programmability for broad application, insensitivity to process and temperature variations, and few external components. Experimental results are provided for a 400 W HID electronic ballast
