... POWER FACTOR CORRECTION CONTROLLER General Description The AP1661 is an active power factor control IC which is designed mainly for use as pre-converter in elec- tronic ballast, AC-DC adapters and off-line SMPS applications. The AP1661 includes an internal start-up timer for stand-alone applications, a one-quadrant multiplier to realize near unity power factor and a zero current detector to ensure DCM boundary conduction opera- tion ...

... POWER FACTOR CORRECTION CONTROLLER Functional Block Description AP1661 is a high performance power factor correction controller which operates in DCM boundary conduc- tion mode. The PFC converter's switch will be turned on when the inductor current reduces to zero and turned off when the sensed inductor current reaches the required reference which is decided by the output of multiplier ...
