... Vrms of the except in proportion to the instantaneous line voltage. The PFC section of the CM6802A/B/AH/BH uses a boost-mode DC-DC converter to accomplish this. The input to the converter is the full wave rectified AC line voltage. No bulk filtering is applied following the bridge rectifier, so the input voltage to the boost converter ranges (at twice line frequency) from zero volts to the peak value of the AC input and back to zero ...

... DC I stage over-current protection. No voltage error amplifier is included in the PWM stage of the CM6802A/B/AH/BH, as this function is generally performed on the output side of the PWM’s isolation boundary. To facilitate the design of opto-coupler feedback circuitry, an offset has been built into the PWM’s RAMP2 input which allows V zero percent duty cycle for input voltages below around 1 ...
