DESCRIPTION
L6561 is the improved version of the L6560 stan-
dard Power Factor Corrector. Fully compatible
with the standard version, it has a superior perfor-
mant multiplier making the device capable of work-
ing 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
The totem pole output stage is capable of driving
a Power MOS or IGBT with source and sink cur-
rents of ±400mA. The device is operating in tran-
sition mode and it is optimised for Electronic Lamp
Ballast application, AC-DC adaptors and SMPS.
