UCC28880D

AC/DC CONVERTER, 75KHZ, SOIC-7.

The UCC28880D is a High Voltage Switcher for non-isolated AC/DC conversion, 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 UCC28880D the most common converter topologies, such as buck, buck-boost and flyback can be built using a minimum number of external components. The UCC28880D incorporates a soft-start feature for controlled start up of the power stage which minimizes the stress on the power-stage components.
