my earlier email ,went unanswered….. i need some circuit whiz to design a —–Low Cost / Simple discrete component (may include 555 IC ,but no Custom Ballast ICs..) CIRCUIT—-to light up a 7 watt 4 pin, CFL from a 6 volt 4 AH battery +220 volt mains+3 watt Solar Panel
the idea is to make available, reliable lanterns as product, or as a SKD / CKD KIT form, to enable local assembly for poor
mail from SRM
IRPLCFL2 design has schematic and BOM.
The CFL-2 is an electronic ballast design for driving a 42 watt compact fluorescent lamp from a
120 or 230 volt AC line. The circuit was designed using the IR2156 Ballast Driver IC. The main
features of the circuit are programmable frequency, preheat time, over-current threshold and
