I was considering driving EL wire with Supertex'es ICs or some equivalent ICs from another manufacturer. The ICs are designed to drive EL panels not EL wire. Would this still work?
Supertex'es ICs are rated for "lamp sizes" up to 42 square inch. My wire is 2.3 mm in diameter and 20 meters long. I'm going to assume 2.3 mm is the diameter including the outer protective sleeve and the actual diameter is probably somewhere around 2 mm. Looking up the formula for a cylinder's surface area I determined that my EL wire has surface area of about 2513 cm² (about 390 square inch). That's way too much for those ICs.
According to this calculation I could drive up to 2 meters of EL wire with these ICs. But is this calculation applicable to EL wire at all?
