产品概述
The UCC28061D is a natural interleaving transition-mode Power Factor Correction (PFC) Controller with improved audible noise immunity.
- Easy phase management facilitates compliance to light-load efficient standards
- Sensorless current shaping simplifies board layout and improves efficiency
- Inrush safe current limiting
- Prevents MOSFET conduction during inrush
- Eliminates reverse recovery events in output rectifiers
- Improved audible noise performance
- Soft start on overvoltage
- Integrated brownout
- Improved efficiency and design flexibility over traditional
- Single-phase continuous conduction mode (CCM)
- Input filter and output capacitor current cancellation
- Reduced current ripple for higher system reliability and smaller bulk capacitor
- Reduced EMI filter size
- Enables use of diodes without extensive snubber circuitry
- Improved light-load efficiency
- Improved transient response
- Complete system-level protection
