L6382D(2007) Datasheet PDF - STMicroelectronics

Description
The L6382D is suitable for microcontrolled electronic ballasts embedding a PFC stage and a half-bridge stage. The L6382D includes 4 MOSFET driving stages (for the PFC, for the half bridge, for the preheating MOSFET) plus a power management unit (PMU) featuring also a reference able to supply the microcontroller in any condition.
Besides increasing the application efficiency, the L6382D reduces the bill of materials because different tasks (regarding drivers and power management) are performed by a single IC, which improves the application reliability.

FEATUREs
■ Integrated high-voltage start-up
■ 4 drivers for PFC, half-bridge & pre-heating MOSFETs
■ 3.3V microcontroller compatible
■ Fully integrate power management for all operating modes
■ Internal two point VCC regulator
■ Over-current protection with digital output signal
■ Cross-conduction protection (interlocking)
■ Under voltage lock-out
■ Integrated bootstrap diode

APPLICATIONs
■ Dimmable / non-dimmable ballast
