OB6561PX - High Performance PFC Controller

This page provides the datasheet information for the OB6561PX, a member of the OB6561PX-On High Performance PFC Controller family.

Datasheet Summary

Description

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

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.
