STEVAL-ILB005V2
for PFC and ballast control
Data Brief
Description
Requirements for modern fluorescent lamp
electronic ballasts focus on driver efficiency and
safety aspects.
Previous dedicated ICs for ballast applications
allowed designers to achieve good driver
efficiency, but they required a lot of external
circuitry to obtain good power factor correction,
low THD and a full set of protection features.
The STEVAL-ILB005V2 demonstration board is
based on the new L6585DE combo IC for ballast
applications, which offers designers a highperformance PFC stage, and a high capability,
fully programmable, half-bridge high-voltage
driver. The device is also equipped with a full set
of protection features.
Designed in high-voltage BCD off-line technology,
the L6585DE embeds a PFC controller, a halfbridge controller, the relevant drivers and all the
logic circuitry necessary to build an electronic
ballast.
STEVAL-ILB005V2
Another important feature of the IC is its capability
to control and limit the lamp voltage during the
ignition phase.
The pre-heating and ignition durations are
independently configurable, as are the half-bridge
switching frequencies for each operating phase
(pre-heating, ignition and normal mode).
Other features, such as half-bridge over-current
with frequency increase and PFC over-voltage,
allow designers to build a reliable, flexible solution
with a reduced component count.
