Description

The UCC28880D is a High Voltage Switcher for non-isolated AC/DC conversion, integrates the controller and a 700V 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 UCC28880D the most common converter topologies, such as buck, buck-boost and flyback can be built using a minimum number of external components. The UCC28880D incorporates a soft-start feature for controlled start up of the power stage which minimizes the stress on the power-stage components.
Integrated power MOSFET (switch) rated to 700V 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
<100µA Device quiescent current
Robust performance with inductor current runaway prevention
Current limit, overload, output short-circuit and over-temperature protection
Green product and no Sb/Br
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
