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

µA 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 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

- verylow operating quiescent current minimises

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

transition mode and it is optimised for Electronic

Lamp Ballast application, AC-DC adaptors and

SMPS.
