A demonstration board was developed as an example for Compact Fluorescent Lamp ballast. It is optimised for a CF18DT/E/830 18W lamp from Osram-Sylvania. Using the L6569 the circuit achieves preheat, ignition and normal lamp operation. The power transistors are two STD3NA50 500V-3W MOSFETs in I-PACK package.

The STEVAL-ILB005V2 demonstration board is based on the new L6585DE combo IC for ballast applications, which offers designers a high performance PFC stage, and a high capability, fully programmable, half-bridge high-voltage driver. The device is also equipped with a full set of protection features.
