Description

The STEVAL-ILB008V1 is a wide-range lighting
ballast capable of driving 4 x 18 W linear T8
fluorescent tubes.

The ballast is controlled by the L6585DE IC,
which integrates PFC and half-bridge control
circuits, relevant drivers, and the circuitry required
to manage all lamp operating phases (pre­heating, ignition and run mode). Protection
against failures such as lamp disconnection, anti­capacitive mode, and PFC overvoltage are
guaranteed and achieved using a minimum
number of external components.

STEVAL-ILB008V1

An electronic ballast consumes less power and
therefore dissipates less heat than an
electromagnetic ballast. The energy saved is
estimated to be in the range of 20-25% for a given
lamp power. Moreover, an electronic solution
allows for improved control of the filament current
and lamp voltage during pre-heating, resulting in
increased lamp life.
