Runaway Prevention
• Thermal Shutdown
• Protection
– Current Limit
– Overload and Output Short Circuit
• Create a Custom Design Using the UCC28880
with the WEBENCH Power Designer
2 Applications
• AC-to-DC Power Supplies
(Output Current Up to 100 mA for CCM;
70 mA for DCM)
• Metering, Home Automation, Infrastructure SMPS
• Low-Side Buck Topology for TRIAC Driver
• Appliances, White Goods and LED Drivers
3 Description
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.
