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 ...
