Part Number : UCC28880
Function : 700-V Lowest Quiescent Current Off-Line Switcher
Package : SOIC 7 Pin Type
Manufacturers : Texas Instruments
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 device the most common converter topologies, such as buck, buck boost and flyback can be built using a minimum number of external components. The IC incorporates a soft-start feature for controlled start up of the power stage which minimizes the stress on the power-stage components.
1. Self-Biased Switcher (Start Up and Operation Directly from Rectified Mains Voltage)
2. Supports Buck, Buck-Boost and Flyback Topologies
3. <100-μA Device Quiescent Current
4. Robust Performance with Inductor Current Runaway Prevention
