DESCRIPTION
RS2330 is an active transition-mode (TM) power-factor-correction (PFC) controller for AC/DC switching mode power supply applications.
RS2330 features an internal start-up time for stand-alone applications, a quadrant multiplier with THD optimizer for near unity power factor, zero current detector (ZCD) to ensure TM operation, a current sensing comparator with built-in leading-edge blanking, and a totem pole output ideally suited for driving a power MOSFET.
