APPLICATIONS
DIMMABLE/NON-DIMMABLE BALLST
plications managed by a microcontroller. It allows
the designer to use the same ballast circuit for dif-
ferent lamp wattage/type by simply changing the
碌C
software.
The digital input pins - able to receive signals up to
400KHz - are connected to level shifters that pro-
vide the control signals to their relevant drivers; in
particular the L6382D5 embeds one driver for the
PFC pre-regulator stage, two drivers for the ballast
