DESCRIPTION

· The KA7541 offers high-performance electronic ballast control with minimal board space and low power dissipation.
· Optimized for electronic ballasts, it reduces component count and integrates soft start circuitry, eliminating the need for external PTC resistors.
· Features protection against switch burnout in no-lamp conditions and clamps MOSFET gate voltage regardless of supply voltage.

FEATURES

· Internal soft start with adjustable frequency and time.
· No lamp protection 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 electronic ballasts requiring compact design and efficient operation.
· Suitable for various lamp types with customizable soft start settings.
· Ensures reliable performance in no-lamp scenarios.
