Device description
Designed in High-voltage BCD Off-line technology, the L6382D is a PFC and ballast
controller provided with 4 inputs pin and a high voltage start-up generator conceived for
applications managed by a microcontroller providing the maximum flexibility. It allows the
designer to use the same ballast circuit for different lamp wattage/type by simply changing
the
μ
C software.
The digital input pins - able to receive signals up to 400KHz - are connected to level shifters
that provide the control signals to their relevant drivers; in particular the L6382D embeds
one driver for the PFC pre-regulator stage, two drivers for the ballast half-bridge stage (High
Voltage, including also the bootstrap function) and the last one to provide supplementary
features like preheating of filaments supplied through isolated windings in dimmable
applications.
A precise reference voltage (+3.3V ±1%) able to provide up to 30mA is available to supply
the
μ
C: this current is obtained thanks to the on-chip high voltage start-up generator that,
moreover, keeps the consumption before start-up below 150
μ
A.
The chip has been designed with advanced power management logic to minimize power
losses and increase the application reliability.
In the half-bridge section, a patented integrated bootstrap section replaces the external
bootstrap diode.
The L6382D integrates also a function that regulates the IC supply voltage (without the need
of any external charge pump) and optimizes the current consumption.
