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 (<100-μA) 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. It offers robust performance with inductor current runaway prevention. Protections are in place for: current limit, overload and output short circuit, and over temperature. Applications include AC-to-DC power supplies (with output currents up to 100 mA across temperature and input voltage range); metering, home automation, infrastructure SMPS; low-side buck topology for TRIAC driver; and appliances and LED drivers.
