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.
• 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
• 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
