Product Summary

The L6561D is a Power Factor Corrector. Fully compatible with the standard version, the L6561D has a superior performant multiplier making the L6561D capable of working in wide input voltage range applications (from 85V to 265V) with an excellent THD. Furthermore the start up current has been reduced at few tens of mA and a disable function has been implemented on the ZCD pin, guaranteeing lower current consumption in stand by mode. The totem pole output stage is capable of driving a Power MOS or IGBT with source and sink currents of +/- 400mA. The L6561D is operating in transition mode and it is optimized for Electronic Lamp Ballast application, AC-DC adaptors and SMPS.
