OB6566 - High Performance PFC Controller

Download the OB6566 datasheet PDF. This datasheet also covers the OB6566-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

OB6566 is an active transition-mode (TM) power factor correction (PFC) controller for AC-DC switching mode power supply applications.

Key Features

  • a demagnetization detector 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. OB6566 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, Inductor short protection(ISP), and gate drive output clamping for external power MOSFET protection. With.
