KA7540 Datasheet Simple Dimming Ballast Control Ic

Manufacturer: Samsung Semiconductor

Overview: .fairchildsemi. KA7540 Simple Dimming Ballast Control IC.

General Description

s 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.

Key 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.
