Device description
Designed in High-voltage BCD Off-line technology, the L6585D embeds a PFC controller, a
half-bridge controller, the relevant drivers and the logic necessary to build an electronic
ballast.
The advanced and precise logic circuitry, combined with the programmability of the End-of-
Life windows comparator threshold, makes the L6585D compliant with either "lamp-to-
ground" or "block capacitor-to ground" configurations.
Another outstanding feature is the possibility of controlling and limiting the lamp voltage
during the ignition phase.
The pre-heating and ignition durations are independently settable as well as the half-bridge
switching frequencies for each operating phases (pre-heating, ignition and normal mode).
Other features (half-bridge over-current with frequency increase, PFC over-voltage) allow
building a reliable and flexible solution with a reduced part count.
The PFC section achieves current mode control operating 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.
The PFC output voltage is controlled by means of a voltage-mode error amplifier and a
precise internal voltage reference.
The driver of the PFC is able to provide 300mA (source) and 600mA (sink) and the drivers of
the half-bridge provide 290mA source and 480mA sink.
