This is Advanced transition-mode PFC controller. The device is a current-mode PFC controller operating in Transition Mode (TM). Based on the core of a standard TM PFC controller, it offers improved performance and additional functions.

The highly linear multiplier, along with a special correction circuit that reduces crossover
distortion of the mains current, allows wide-range-mains operation with an extremely low
THD even over a large load range


1. Transition-mode control of PFC pre-regulators

2. Very precise adjustable output overvoltage protection

3. Tracking boost function

4. Protection against feedback loop failure (Latched shutdown)

5. Interface for cascaded converter’s PWM controller

6. Input voltage feedforward (1/V2)

7. AC brownout protection […]
