L6585D Combo IC for PFC and ballast control

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.
