The UCC3808ADTR-1G4 is designed to provide power management solutions for a variety of applications, including PCB layout and system design. The UCC3808ADTR-1G4 is also a suitable solution for power adapter design.

The working principle of this device is based on a peak-current-mode control. This type of control helps to achieve high efficiency, high output accuracy, and good line/ load regulation. The peak-current-mode control continuously monitors the main switch current feedback signal and provides the necessary information to the internal controller. The controller captures the input current and adjusts the switch on time according to the current feedback signal.

The UCC3808ADTR-1G4 has a high voltage (HV) dedicated power MOSFET, which provides excellent efficiency and excellent output accuracy. The device also incorporates a Line Undervoltage (UVLO) function, which protects the device from overload and under voltage. The under voltage protection is triggered if the input voltage falls below the adjustable voltage threshold. If the input voltage is lower than the UVLO threshold, the device shuts down and resumes operation when the input voltage rises to the threshold voltage.

The UCC3808ADTR-1G4 has a fixed frequency oscillator, which helps to maintain a stable output without any additional circuitry. The frequency is adjustable from ~50 kHz to ~300 kHz, and it can be programmed using an external resistor. The device also incorporates various safety features such as over temperature protection, over current protection, and over voltage protection.
