OB6573 8 Pin CCM PFC Controller with Frequency Shuffling Product Specification GENERAL DESCRIPTION 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. The IC allows major reductions in Bill of Materials (BOM) component count, PCB area and design time compared to traditional solutions. The switching frequency of OB6573 is trimmed and fixed internally at 65KHz. To achieve good EMI performance, the built-in frequency shuffling is provided. Both compensation for the voltage loop and the current loop are external to allow full user control. Fast 1.
