1 / 13 page 1/13 L6561 June 2004 1 FEATURES ■ VERY PRECISE ADJUSTABLE OUTPUT OVERVOLTAGE PROTECTION ■ MICRO POWER START-UP CURRENT (50 µA TYP.) ■ VERY LOW OPERATING SUPPLY CURRENT(4mA TYP.) ■ INTERNAL START-UP TIMER ■ CURRENT SENSE FILTER ON CHIP ■ DISABLE FUNCTION ■ 1% PRECISION (@ Tj = 25°C) INTERNAL REFERENCE VOLTAGE ■ TRANSITION MODE OPERATION ■ TOTEM POLE OUTPUT CURRENT: ±400mA ■ DIP-8/SO-8 PACKAGES 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. 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. POWER FACTOR CORRECTOR Figure 2.
