DESCRIPTION

· The KA7541 offers high-performance electronic ballast control with simplicity.

· Designed for electronic ballasts, it minimizes board space, reduces component count, and lowers power dissipation.

· Features internal soft start circuitry, eliminating the need for external PTC resistors.

· Includes protection circuitry to prevent switch burnout in no-lamp conditions.

· Output gate drive circuit clamps MOSFET gate voltage regardless of supply voltage.

FEATURES

· Internal soft start functionality.

· Adjustable soft start frequency and time based on lamp type.

· No lamp protection feature included.

· Precision internal bandgap reference trimmed to 1.5%.

· Under voltage lockout with 1.8V hysteresis.

· Totem pole output with high state clamp.

· Low startup and operating current.

APPLICATIONS

· Ideal for use in electronic ballasts requiring efficient and compact design.
