FEATURES

DESCRIPTION

•

Regulates Lamp Power

The UCC3305 integrates all of the functions required to control and drive one

HID lamp. The UCC3305 is tailored to the demanding, fast turn-on requirements

of automobile headlamps, but is also applicable to all other lighting applications

where HID lamps are selected. HID lamps are ideal for any lighting applications

that can benefit from very high efficiency, blue-white light color, small physical

lamp size, and very long life.

•

Compensates For Lamp

Temperature

•

Fixed Frequency Operation

Current Mode Control

The UCC3305 contains a complete current mode pulse width modulator, a lamp

power regulator, lamp temperature compensation, and total fault protection.

Lamp temperature compensation is critical for automobile headlamps, because

without compensation, light output varies dramatically from a cold lamp to one

that is fully warmed up.

Overcurrent Protected

Overvoltage Shutdown

Open and Short Protected

High Current FET Drive Output

The UCC2305 is tested for full performance with ambient temperature

from –40°C to +105°C while the UCC3305 is tested with ambient temperature

from 0°C to +70°C. The UCC3305 is available in a 28 pin small-outline, surface

mount plastic package (SOIC).

Operates Over Wide Battery

Voltage Range: 5V to 18V
