OB6561PX - High Performance PFC Controller

Download the OB6561PX datasheet PDF. This datasheet also covers the OB6561PX-On variant, as both devices belong to the same high performance pfc controller family and are provided as variant models within a single manufacturer datasheet.

General Description

OB6561PX is an active transition-mode (TM) power factor correction (PFC) controller for ACDC switching mode power supply applications.

Key Features

  • 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 built-in leadingedge blanking, and a totem pole output ideally suited for driving a power MOSFET. OB6561PX 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 th.
