Description
The R2A20111 is a power-factor correction (PFC) controller IC. This IC adopts
continuous conduction mode as PFC operation. Various functions such as
constant power limit, overvoltage detection, overcurrent detection, soft
start, feedback-loop disconnection detection, and holding function of PFC
operation through momentary outage (PFC hold function) are incorporated in a
single chip. These functions reduce external circuitry.
The constant power limit function allows to eliminate a significant amount of
coil noise which is generated due to overcurrent detection operation in case
of conventional overload. The PFC hold function enables quick recovery by
continuing PFC operation after momentary outage. The hold time can be adjusted
by an external capacitance. Overcurrent detection pin is separately provided.
Latch mode shutdown function is incorporated. 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.
