DIP-8/SO-8 PACKAGES,

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 implemented 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 current sense
– very low operating quiescent current minimises power dissipation
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.
