The UCC28C45DGKG4 by Texas Instruments is an advanced self-protection phase-shift full bridge driver for switching power supplies. It is a DC-to-DC switching controller primarily used in applications such as telecom, servers, notebook and game console power supplies and other AC/DC and DC/DC applications. This IC provides several unique features which makes it suitable for such applications.

Working Principle:

UCC28C45DGKG4 operates by having two opposing MOSFET driver outputs that operate in push-pull. By having a constant frequency, it can latch on and off rapidly which allows the IC to improve efficiency and reduce electromagnetic interference (EMI). Each driver will have an active low-side switch and a high-side switch that can be independently controlled by the logic level on their respective input pins. Additionally, the high and low side drivers each feature an output current limit function with separately programmable delay time. This allows the IC to control the current passing through the MOSFET and protect the other components in the application.

Application Fields:

UCC28C45DGKG4 is suitable in AC/DC and DC/DC applications where optimal efficiency, improved EMI performance and high quality are needed. Telecom, server, notebook and game console applications are ideal environments to use this IC since it’s extremely reliable and versatile. It can be especially useful in applications that require high efficiency and low EMI. This IC can also be used in solar and automotive applications since it operates well at high temperatures and low voltage levels.

In addition, this IC can be used in a wide range of automation and control applications such as industrial motor control, robotics, instrumentation and commercial refrigeration. UCC28C45DGKG4 is also well suited for universal AC to DC input applications such as LED driver and power electronics.

In Summary:

In summary, the UCC28C45DGKG4 by Texas Instruments is a DC-to-DC switching controller primarily used in applications such as telecom, servers, notebook and game console power supplies and other AC/DC and DC/DC applications. This IC provides several unique features which makes it suitable for such applications such as active low-side and high-side switches with output current limit and separately programmable delay time. It can be especially useful in applications that require high efficiency and low EMI and is also suitable in a wide range of automation and control applications. All in all, the UCC28C45DGKG4 is a great choice for many power applications.
