This datasheet provides details of the STEVAL-ILB007V1 demo board, which can drive 2 x 58 W linear T8 fluorescent lamps.
The STEVAL-ILB007V1 is a demonstration board capable of driving two 58 W linear T8 fluorescent tubes. The design utilizes the L6585DE device, which integrates PFC and half-bridge control circuits along with drivers for all lamp operating phases including pre-heating, ignition, and run mode.
The electronic ballast solution offers several advantages over electromagnetic alternatives, consuming less power and dissipating less heat, resulting in an estimated energy saving of 20-25%. Additionally, the design provides better control of filament current and lamp voltage during pre-heating to increase lamp life.
