Description
R2A20115 is a power-factor correction (PFC) controller IC, which employs continuous conduction mode as PFC control mode. Various kinds of functions such as constant power limit, overvoltage detection, overcurrent detection, soft start function, feedback-loop open detection, and the function holding its operation through momentary outage (PFC hold function) are incorporated in a single chip. These functions reduce external circuitry.
