Technical Overview
The L6585 is a ballast control IC with integrated Power Factor Corrector (PFC), designed in
High-voltage BCD Off-line technology. This one-chip solution replaces a half bridge
controller, a PFC controller, the relevant drivers and the logic necessary to build an
electronic ballast.
The pre-heating and ignition durations are independently settable as well as the half-bridge
switching frequencies for each operating phase (pre-heating, ignition and normal mode) to
serve many different lamp types. Another outstanding feature is the capability of limiting the
voltage applied to the lamp to a constant value during the ignition phase.
The PFC section operates in Transition Mode. The highly linear multiplier includes a special
circuit, able to reduce AC input current distortion, that allows wide-range-mains operation
with an extremely low THD, even over a large load range.
Some IC features, like the under voltage lock-out and the PFC over-voltage and feedback
disconnection controls can assure lamp protection. Furthermore, a double threshold
comparator on the half bridge current sense provides a sort of current control and avoids the
MOSFETs working in the capacitive mode. A double threshold comparator on the PFC
current sense prevents the inductor saturation.
Other features like the automatic re-lamp for lamp replacing, the failure to strike and the
End-Of-Life control, simplify the lamp management. The programmability of the EOL
windows comparator thresholds makes the L6585 the only lighting IC compliant with either
"lamp-to-ground" or "block capacitor-to-ground" configurations.
The driver of the PFC is able to provide 120mA (source) and 250mA (sink) and the drivers
of the half-bridge provide 170mA source and sink.
