UCC28880 700V Lowest IQ Off-Line Switcher

Texas Instruments UCC28880 700V Lowest I Q Off-Line Switcher integrates the controller and a 700V power MOSFET into one monolithic device. The device also integrates a high-voltage current source, enabling start-up and operation directly from the rectified mains voltage. The low quiescent current of the device enables excellent efficiency. With the UCC28880, the most common converter topologies, such as buck, buck-boost, and flyback can be built using a minimum number of external components. The Texas Instruments UCC28880 incorporates a soft-start feature for a controlled start-up of the power stage, which minimizes the stress on the power-stage components.
