STEVAL-ILB005V2: 54W Output, 88 ~ 277V in

The STEVAL-ILB005V2 demonstration board is based on the new L6585DE combo IC for ballast applications, which offers designers a high performance 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 half-bridge controller, the relevant drivers and all the logic circuitry necessary to build an electronic ballast.

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.
