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.DataSheetV4Ua.rcioomus 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*. The continuance time can be adjusted by an
external capacitance.
The PFC output voltage is monitored by checking the Power Good signal. When the power-factor correction is “good,”
the Power Good signal is output after a delay time to secure stabilization of the PFC output voltage; when the power
factor correction is not good, the output is stopped immediately. The delay time and power good stop level are
adjustable by using an external circuit.
PFC operation can be turned on and off by an external control signal. By using this function, PFC operation can be
disabled at low input voltage, allowing remote control from the secondary side.
A soft-start control pin provides for the easy adjustment of soft-start operation, and can be used to prevent overshooting
of the output voltage.
*: For details on the PFC hold function, refer to page 19.
