   How does uc3855a/b work?

   • The UC3855A/B also features a single quadrant multiplier, squarer, and divider circuit which provides the programming signal for the current loop. The internal multiplier current limit reduces output power during low line conditions. An overvoltage protection circuit disables both controller out- puts in the event of a boost output OV condition.

   How does the uc3855 snubbing work?

   • In addition, the UC3855 utilizes an active snubbing or ZVT (Zero Voltage Transition technique) to dramatically reduce diode recovery and MOSFET turn-on losses, result- ing in lower EMI emissions and higher efficiency.
