L6382D：Power Management Unit for Microcontrolled Ballast

The L6382D device is suitable for LED drivers embedding a PFC stage and a half-bridge stage. The L6382D includes 4 MOSFET driving stages (for the PFC, for the half-bridge, and for the auxiliary MOSFET) plus a power management unit (PMU) featuring also a reference able to supply the microcontroller in any condition.

In addition to increasing application efficiency, the L6382D device reduces the bill of materials as different tasks (regarding drivers and power management) are performed by a single IC, which improves application reliability.
