Descriptions
The KA7540 provides simple and high performance
electronic ballast control functions. KA7540 is optimized for
electronic ballast requiring a minimum board area, reduced
component count and low power dissipation. Internal soft
start circuitry eliminates the need for an external soft start
PTC resistor. Voltage controlled dimming circuit is built into
the IC to control the lighting output in a wide range.
Protection circuitry has also been added to prevent switches
from burning out in no lamp condition. Output gate drive
circuit clamps power MOSFET gate voltage irrespective of
supply voltage.
