Texas Instruments Lighting, Ballast Controllers UCC2305DW

The UCC2305DW is a HID lamp controller designed to regulate lamp power and compensate for lamp temperature, making it suitable for applications such as automobile headlamps and other HID lighting systems. It operates over a wide battery voltage range of 5V to 18V and features fixed frequency operation with a current mode control. The device includes multiple protection mechanisms, including overcurrent protection, overvoltage shutdown, and protection against open and short circuits. This controller integrates a complete current mode pulse width modulator, a lamp power regulator, and fault protection, ensuring reliable performance. It is tested for full performance across a temperature range of -40¬8C to +105¬8C. The UCC2305DW is packaged in a 28-pin small-outline, surface mount plastic package (SOIC), making it suitable for compact designs. Its specifications and features make it a viable option for engineers looking to implement efficient HID lighting solutions.
