DESCRIPTION

· The UCC3305 is an integrated controller designed for HID lamps, featuring a complete current mode pulse width modulator, lamp power regulator, temperature compensation, and comprehensive fault protection.

· It is specifically tailored for automotive headlamps with fast turn-on requirements but is also suitable for other HID lighting applications.

· The device operates over a wide battery voltage range from 5V to 18V and is available in a 28-pin SOIC package.

FEATURES

· Fixed frequency operation with current mode control.

· Includes overcurrent protection, overvoltage shutdown, and open/short circuit protection.

· High current FET drive output for efficient lamp control.

· Lamp temperature compensation ensures consistent light output from cold to fully warmed up states.

· Tested for performance across a range of ambient temperatures: UCC2305 from -40°C to +105°C, UCC3305 from 0°C to +70°C.

APPLICATIONS

· Ideal for automotive headlamps and other applications requiring HID lamps.

· Suitable for environments that benefit from high efficiency, blue-white light color, compact lamp size, and extended lamp life.
