.fairchildsemi. Simple Dimming Ballast Control IC Features - - - - - - - - Internal soft start No lamp protection Voltage controlled dimming 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 8-pin DIP & 8-pin SOP Descriptions The KA7540 provides simple and high performance electronic ballast control functions. KA7540 is optimized for electronic ballast requiring a minimum board area, reduced ponent count and low power dissipation. Internal soft start circuitry eliminates the need for an external soft start PTC resistor. Voltage controlled dimming circuit is...
