Product Description

The UCC28061D is a natural interleaving transition-mode Power Factor Correction (PFC) Controller with improved audible noise immunity. By utilizing a Natural Interleaving technique, both channels operate as masters (that is, there is no slave channel) synchronized to the same frequency. This approach delivers inherently strong matching, faster responses and ensures that each channel operates in transition mode. Complete system-level protections feature input brownout, output over-voltage, open-loop, overload, soft-start, phase-fail detection and thermal shutdown. The additional FailSafe over-voltage protection (OVP) feature protects against shorts to an intermediate voltage that, if undetected, could lead to catastrophic device failure.
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
