The L6382D is suitable for microcontrolled electronic ballasts, including a PFC stage and a half-bridge stage, as well as a power management unit (PMU) with a reference voltage output that can supply the microcontroller in any condition.
The L6382D is a power management unit designed for microcontrolled electronic ballasts that embed a PFC stage and a half-bridge stage. It integrates four MOSFET driving stages for the PFC, half-bridge, and pre-heating, along with a power management unit featuring a 3.3V reference voltage to supply a microcontroller.
The device includes advanced power management logic to minimize power losses and increase reliability. Key features include an integrated high-voltage start-up generator, cross-conduction protection, under-voltage lock-out, and over-current protection with a digital output signal. It is suitable for both dimmable and non-dimmable ballast applications.
