L6561 is the improved version of the L6560 standard Power Factor Corrector. It has a superior performance 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. Realised in mixed BCD technology, the chip gives the following benefits: – micro power start up current – 1% precision internal reference voltage – (Tj = 25°C) – Soft Output Over Voltage Protection – no need for external low pass filter on the cur- rent sense – very low operating quiescent current minimis- es power dissipation
