HA16174P/FP Power Factor Correction Controller IC REJ03D0789-0100 Rev.1.00 Jan 06, 2006 Description The HA16174P/FP is a power-factor correction (PFC) controller IC. This IC adopts continuous conduction mode as PFC operation. www.DataSheet4U.com Various functions such as over voltage detection, over current detection, soft start, feedback-loop disconnection detection, Power Good signal output, and holding function of PFC operation through momentary outage (PFC hold function) are incorporated in a single chip. This eliminates a significant amount of external circuitry. The PFC function enables the continuation of PFC operation for a specified period when a momentary outage occurs, so that quick recovery after a sufficiently momentary outage is achieved*.
