TEXAS INSTRUMENTS UCC28881D 芯片, 离线式开关, 75KHZ, SOIC-7 新
The UCC28881 integrates the controller and a 14-Ω, 700-V 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. UCC28881 is the same family device of UCC28880, with higher current handling capability.
The low quiescent current of the device enables excellent efficiency. With the UCC28881 the most common converter topologies, such as buck, buck-boost and flyback can be built using a minimum number of external components.
The UCC28881 incorporates a soft-start feature for controlled start up of the power stage which minimizes the stress on the power-stage components.
