AP1662 Description
The AP1662 is an active power factor control IC which is designed mainly for use as a pre-converter in electronic ballast, AC-DC adapter and off-line SMPS applications. The IC 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 operation. The totem pole output stage is capable of...
