8-Pin CCM PFC Controller

OB6572/OB6573 is 8-pin Power Factor Correction (PFC) controller IC designed to operate in Continuous Conduction Mode (CCM) with average current control. It provides near-unity power factor for universal input line voltage (85VAC-265VAC) with no need to sense the input voltage.
