UCC28880
High voltage switcher for Non-isolated AC/DC Conversion
UCC28880
- Integrated Power MOSFET (Switch) Rated to
700-V Drain-to-Source Voltage - Integrated High-Voltage Current Source for Internal Low-Voltage Supply Generation
- Soft Start
- Self-Biased Switcher (Start Up and Operation Directly from Rectified Mains Voltage)
- Supports Buck, Buck-Boost and Flyback Topologies
- <100-μA Device Quiescent Current
- Robust Performance with Inductor Current Runaway Prevention
- Thermal Shutdown
- Protection
- Current Limit
- Overload and Output Short Circuit
The UCC28880 integrates the controller and a 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.
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 UCC28880 incorporates a soft-start feature for controlled start up of the power stage which minimizes the stress on the power-stage components.
