The UC2872Q is a versatile function integrated circuit (IC) that is capable of operating in a wide variety of lighting and ballast control applications. It features a highly efficient power converter topology that is capable of supplying the high current demands of most lighting and ballast control projects. It’s small size and versatility make it a great choice for many applications.The UC2872Q is a high efficiency switching regulator which is capable of providing up to 2A of load current while operating over a wide range of input voltages. The UC2872Q comes in two versions, 1A and 5A. The 1A version is suited for lighting applications requiring low current applications, while the 5A version is best suited for more demanding applications such as ballast control.The UC2872Q utilizes a single inductor for power conversion, with the switching current paths being gathered around the perimeter of the IC. This helps reduce the overall package size and power dissipation associated with the IC. The IC is protected against over temperature, short circuit and overload conditions, and is protected against input under voltage.The IC can be operated in either a buck or a boost mode depending on the input voltage and the output current requirements. In buck mode, the IC will convert the input voltage to an output voltage that is lower than the input voltage. In boost mode, the IC will convert the input voltage to an output voltage that is higher than the input voltage.The IC also features a broad range of control and protection features. The protection features provided by the UC2872Q include input under voltage and over voltage protection, over temperature protection, overcurrent limit and thermal shutdown protection. The IC can be configured to operate in either a constant voltage or constant current mode, allowing the user to program the output voltage and current to the desired values.The UC2872Q is an excellent solution for lighting and ballast control applications, offering high efficiency, small size and versatile control features. The integrated protection features and high efficiency design make it a very cost effective solution for many applications.
