UCC28060DG4, PFC контроллер, 14В до 21В и 5мА, 14В отключение, 100% коэффициент заполнения, 0.5МГц, SOIC-16

The UCC28060DG4 is a natural interleaved dual-phase transition-mode Power Factor Correction (PFC) Controller utilizes 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.

• Inrush safe current limiting
• Prevents MOSFET conduction during inrush
• Eliminates reverse recovery events in output rectifiers
• Enables Use of diodes without extensive snubber circuitry
• Improved light-load efficiency
• Improved transient response
• Complete system-level protection
• Reduced current ripple for higher system reliability and smaller bulk capacitor
• Reduced EMI filter size
• Input filter and output capacitor current cancellation
• Green product and no Sb/Br
