OB6573 - 8 Pin CCM PFC Controller
OB6573 is a 8-pin active power factor correction (PFC) controller 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 line input voltage.
