L6561 is the improved version of the L6560 standard Power Factor Corrector. Fully compatible with the standard version, it has a superior performant multiplier making the device 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 implement ed on the ZCD pin, guaranteeing lower current consumption in stand by mode.
