L6561 is the improved version of the L6560 standard Power Factor Corrector. Fully compatible with the standard version, it has a superior performing 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 to a few tens of mA and a disable function has been implemented on the ZCD pin, guaranteeing lower current consumption in standby mode.
Realised in mixed BCD technology, the chip gives the following benefits:
The totem pole output stage is capable of driving a Power MOS or IGBT with source and sink currents of ±400mA. The device is operating in transition mode, and it is optimised for Electronic Lamp Ballast application, AC-DC adaptors, and SMPS.
