application INFO available UCC2305 UCC3305 HID Lamp Controller FEATURES DESCRIPTION • Regulates Lamp Power • Compensates For Lamp Temperature • Fixed Frequency Operation • Current Mode Control 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. • Overcurrent Protected • Overvoltage Shutdown • Open and Short Protected • High Current FET Drive Output • Operates Over Wide Battery Voltage Range: 5V to 18V 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. 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).
