Description

The HA16178P/FP is a power-factor correction (PFC) controller IC.

This HA16178P/FP IC adopts continuous conduction mode as PFC operation.

Various functions of HA16178P/FP 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.

HA16178P/FP 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.
