L6561D Description

Short technical summary and product information.

The STMicroelectronics L6561D is a Power Factor Correction (PFC) controller IC operating in discontinuous (transition) mode. It is housed in a standard 8-SOIC package suitable for surface mounting.

 

This component is designed to operate within a voltage range of 11V to 18V, with a low quiescent current of 50 µA. The operating temperature range is specified from -25°C to 125°C, making it suitable for various environmental conditions.

 

The L6561D is RoHS3 compliant, has an MSL of 1, and is REACH unaffected, indicating adherence to common environmental and safety standards. Its primary function is to improve power factor in power supply designs.

 

Applications for this PFC controller include power supplies where power factor correction is required to meet regulatory standards or improve efficiency. The surface mountable 8-SOIC package facilitates integration into compact electronic designs.
