R2A20111SP#W0 - Renesas Electronics
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
