IW2202 Description
The iW2202 is a digital switching mode power supply controller for PFC applications. Its is typically used with the PFC-corrected BIFRED (Boost Integrated with Flyback Rectifier/Energy storage DC/DC) topology, shown in Figure 1. The BIFRED topology is a singlestage, single-switch topology that bines a boost converter with an isolated flyback converter, achieving power-factor correction with a low parts count.
