The Texas Instruments UCC28C44DGK is a member of their GreenPoint™ product family which forms part of their portfolio of AC/DC converters, offline switchers and other power management ICs (PMICs) for mission-critical applications.

UCC28C44DGK is a highly integrated, 1700-VA rated power management IC (PMIC). An integrated 725-V MOSFET provides a full-wave rectification circuit and bidirectional energy flow capability, allowing it to accept power from either an AC or DC source. The UCC28C44DGK’s feedback outputs enable a wide range of AC/DC and DC/DC applications, including battery back-up systems and UPSs, motor control, motor speed control, dedicated solar cell control, and off-grid applications like lighting and bootstrapping.

The UCC28C44DGK includes a series of features that make it ideal for design into highly efficient, rugged, and reliable applications with demanding requirements. These features include a built-in 5A output current limit and 3 uA input bias current to conserve power. Also, integrated soft-start circuitry and internal current limiting capabilities improve the robustness of the device and help it meet system requirements for inrush current peaks and overvoltage protection. Further, the UCC28C44DGK is tested and guaranteed to fit both efficiency and power requirements of the SRP2030N/2031N system requirements.

UCC28C44DGK\'s working principle is based on the principle of AC/DC conversion. When an AC voltage is applied to the input, the UCC28C44DGK\'s rectifier bridge rectifies the voltage and the output voltage is regulated by the feedback components. The integrated 725V MOSFET helps limit the power by increasing efficiency and lowering the amount of heat dissipated by the system. The output voltage can also be regulated by the feedback components with a resistor and/or capacitor connected at the output.

Additionally, the UCC28C44DGK includes several features to help improve system reliability. For instance, it integrates UVLO (undervoltage Lock Out) and OVP (overvoltage protection) for automatic power shutdown if the input voltage is outside of the specified range. The UCC28C44DGK also integrates current limit protection to prevent damage from excessive current draw, current sharing for output currents up to 7.5A, and comprehensive fault diagnostics over the SMBus interface.

In conclusion, the Texas Instruments UCC28C44DGK is a highly integrated PMIC, ideal for implementing AC/DC and DC/DC applications. Its integrated features and comprehensive fault diagnostics make it a great choice for mission-critical applications needing a reliable and efficient power management solution.
