Voltage Range: 5V to 18V
The UCC3305 integratesallof the functions requiredto control and drive one
HID lamp. The UCC3305is tailoredto the demanding, fast turn-on requirements automobile headlamps, butis also applicabletoall other lighting applications
where HID lamps are selected. HID lamps are idealfor any lighting applications
that can benefit from very high efficiency, blue-white light color, small physical
lamp size, and very long life.
The UCC3305 containsa complete current mode pulse width modulator,a lamp
power regulator, lamp temperature compensation, and total fault protection.
Lamp temperature compensationis critical for automobile headlamps, because
without compensation, light output varies dramatically froma cold lampto one
that is fully warmed up.
The UCC2305 is tested for full performance with ambient temperature
from –40°Cto +105°C while the UCC3305is tested with ambient temperature
from 0°Cto+70°C. The UCC3305is availableina28 pin small-outline, surface
mount plastic package (SOIC).
