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.

Table 1. Order Codes
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-
– very low operating quiescent current minimis-
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.

    ... The output voltage is expected to be kept by the operation of the PFC circuit close to its nominal value. This is set by the ratio of the two external resistors R1 and R2 (see fig. 5), taking into consideration that the non inverting input of the error amplifier is biased inside the L6561 at 2.5V. ...
