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.
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
Applications
? Electronic Ballast
? Lighting Control System
? Half-bridge Drive Control System
