DESCRIPTION
L6561 is the improved version of the L6560
standard Power Factor Corrector. Fully compat-
ible with the standard version, it has a superior
performant multiplier making the device capable
of working in wide input voltage range applica-
tions (from 85V to 265V) with an excellent THD.
Furthermore the start up current has been re-
duced at few tens of
μ
A and a disable function
has been implemented on the ZCD pin, guaran-
teeing lower current consumption in stand by
mode.
Realised in mixed BCD technology,the chip gives
the followingbenefits:

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
transition mode and it is optimised for Electronic
Lamp Ballast application, AC-DC adaptors and
SMPS.
