UCC2806DW General Description

The UCC2806DW is a pulse width modulation (PWM) controller designed for controlling power supply circuits in applications such as isolated and non-isolated offline flyback converters. This device operates at a fixed frequency of 50 kHz and features a voltage feedforward design to provide stable and accurate output voltage regulation. The UCC2806DW offers protection features such as overcurrent protection, overvoltage protection, and thermal shutdown to ensure the safety and reliability of the power supply circuit. It also includes soft start and automatic restart functions for smooth power supply startup and fault recovery. This PWM controller has a wide input voltage range of 10 V to 18 V, making it suitable for various power supply designs. The UCC2806DW comes in a 16-pin SOIC package, making it easy to integrate into circuit layouts. Its compact size and high efficiency make it an ideal choice for power supply designs in various applications, including industrial equipment, telecommunication systems, and consumer electronics

Shipping 45 days to mordovia, track was not tracked. Outwardly satisfactory quality, the resistance of the drain of the source corresponds to the declared characteristics, within 0,5 ohms. In the work has not yet checked, well, i think. That the quality corresponds to the declared.
