Electronic Ballast Controller
Features Internal soft start Flexible soft start frequency No lamp protection Trimmed 1.5% internal bandgap reference Under voltage lock out with 1.8V of hysteresis Totem pole output with high state clamp Low start up and operating current
DescriptionsThe KA7541 provides simple and high performance
electronic ballast control functions. KA7541 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. The initial soft start switching frequency and
soft start time can be adjusted depending on the types of
lamps. Protection circuitry has also been added to prevent
burning out of switches in no lamp condition. output gate
drive circuit clamps power MOSFET gate voltage
irrespective of supply voltage
