IVCC1104 Description
The IVCC1104 is a high-speed, precise and pact totem-pole PFC analog controller. IVCC1104 employs the advanced average current mode and fixed-ratio input voltage feedforward control. The control generates a duty cycle baseline D’ = Vin/400V, while the current loop just provides small duty cycle adjustment.
