Descriptions
The KA7543 is an advanced lamp current feedback dimming
control IC. This ballast control IC provides all of the
necessary features to implement wide range dimming
control, soft start and constant power consumption for
intelligent electronic ballast systems. The KA7543 is
optimized for advanced electronic ballast systems requiring
minimum board area. External component counts can be
reduced by adopting the KA7543. Current feedback control
method of the inverter status is one of the most attractive
merits in KA7543. Internal soft start circuitry eliminates the
need for external soft start discrete components. Voltage
controlled soft dimming circuit is built into the IC to control
the lighting output in a wide range. Protection circuitry, no
lamp protection, abnormal protection, one lamp detection,
UVLO, restart on lamp adding , have been added.
