The UC2855BDWTRG4 has all of the control features required for high-power, high-frequency PFC boost converters.
The average current modecontrol method enables stable, low-distortion AC line current programming without the need for slope compensation. Furthermore, the UC2855BDWTRG4 employs active snubbing or ZVT (Zero Voltage Transition technique) to dramatically reduce diode recovery and MOSFET turn-on losses, resulting in lower EMI emissions and higher efficiency.
