The UC3855ADWTRG4 has all of the control features required for high-power, high-frequency PFC boost converters.
The average current mode control method enables stable, low-distortion AC line current programming without the need for slope compensation. Furthermore, the UC3855 employs active snubbing or ZVT to significantly reduce diode recovery and MOSFET turn-on losses, resulting in lower EMI emissions and higher efficiency.UC3855ADWTRG4
