| Description | OB6563 is an active transition-mode (TM) power factor correction (PFC) controller for AC-DC switching mode power supply applications. OB6563 features an internal start-up timer for stand-alone applica... |
| Features |
an internal start-up timer for stand-alone applications, a one quadrant multiplier with THD optimizer for near unity power factor, zero current detector (ZCD) to ensure TM operation, a current sensing comparator with builtin leading-edge blanking, and a totem pole output ideally suited for driving a power MOSFET. OB6563 offers great protection coverage including system over-voltage protection (OVP) to eliminate runaway output voltage due to load removal, VCC under voltage lockout (UVLO), cycle-by-cycle current limiting, multiplier output clamping that limit maximum peak switch current, and gat... |
