UCC2806Q is a high-performance DC-DC buck controller with synchronous rectification technology. This device is designed to operate a synchronous buck converter which provides solution to applications where both cost-effectiveness and high performance is desired. UCC2806Q is an ideal choice for low output voltage, high switching frequency and tight ripple specifications such as automotive, industrial, communication and computing power systems.

UCC2806Q applications include distributed DC power supply, motor drives, LED drivers, data storage, servers and microprocessor core power supplies. It provides cost effective, high efficiency and reliable power conversion solutions for power sensitive applications. The key advantages of UCC2806Q are improved efficiency, better transient response, reduced output noise and lower total cost of ownership.

The working principle of UCC2806Q is based on a buck converter operating with synchronous rectification. When the switching device (usually MOSFET) turns on, energy stored in the inductor is transferred to the output capacitor. When the device turns off, the energy stored in the output capacitor, which is called the output voltage, is kept constant by a constant-voltage feedback loop. The UCC2806Q features a selectable current-mode architecture, adjustable duty cycle and fast response time. It also provides conventional control loop compensation and flexible delay times to extend the control loop bandwidth at high frequencies. The device also includes protection functions for overvoltage, undervoltage, overcurrent, over temperature and open loop operation.

UCC2806Q is a key component in modern DC-DC buck converter designs. It combines high efficiency, cost-effectiveness and improved performance. With its wide range of features, UCC2806Q can be used in a variety of applications requiring efficient and reliable switching power supplies.
