STEVAL-ILB008V1

4 x 18 W wide-range ballast based on the L6585DE combo IC

Features

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 (pre-

heating, ignition and run mode). Protection

against failures such as lamp disconnection, anti-

capacitive mode, and PFC overvoltage are

guaranteed and achieved using a minimum

number of external components.

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.
