STMicroelectronics L6561D013TR, PFC Controller, 70 KHz, 18 V 8-Pin, SO-8

The STMicroelectronics Power Factor Corrector IC 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 implemented on the ZCD pin, guaranteeing lower current consumption in stand by mode.
