HA16178P/FP
Power Factor Correction Controller IC
REJ03D0903-0100
Rev.1.00
Jun 12, 2007
Description
The HA16178P/FP is a power-factor correction (PFC) controller IC.
This IC adopts continuous conduction mode as PFC operation.
Various functions such as over voltage detection, over current detection, soft start, feedback-loop disconnection
detection, are incorporated in a single chip. This eliminates a significant amount of external circuitry.
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.
