The UCC2808D-2 is a voltage regulator and DC DC switching controller that is commonly used in power converters for applications such as microprocessor power supplies, battery chargers, and switch-mode power supplies. It is a single chip solution for conversion of unregulated DC input voltage to the regulated output voltages.

The device comes with advanced protections and a wide range of features including an adjustable pass current, an adjustable reference voltage, a thermal shutdown protection, and undervoltage and overvoltage lockout. It also provides a short circuit regulator with adjustable time delay for integration in high power PFC/PWM converters.

UCC2808D-2 has an on-chip voltage regulator that controls the output voltage when the input voltage exceeds or falls below the set levels. This ensures the output voltage is stable and without any abrupt changes. The device is available in a 16-lead SOIC package and operates over a wide temperature range of -40°C to 125°C.

UCC2808D-2 is based on a switching control and feedback loop circuit that helps in ensuring a precise output voltage regulation. It has an error amplifier and adjustable reference for efficiently controlling the switching duty cycle. The error amplifier is the core component of the device and it compares the input voltage with the reference voltage and controls the switching duty cycle accordingly.

The device provides a feature called dead-time control that helps in avoiding cross conduction. The peak current level and deadtime are adjustable as per the load requirements. The device also features a thermal shutdown protection that protects it from any thermal damage due to prolonged operation.

The UCC2808D-2 device is a powerful voltage regulator and DC DC switching controller that offers a robust and reliable solution for voltage regulation and control in applications. The device\'s features and advanced protection make it an ideal choice for on-board applications where performance, reliability and accuracy are of utmost importance.
