L6382D
Power management unit
for microcontrolled ballast
SO-20
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.
