■ TRANSITION MODE OPERATION

■ TOTEM POLE OUTPUT CURRENT: ±400mA

■ DIP-8/SO-8 PACKAGES

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

2 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.

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.
