ST L6561D

Прерывистый (переходный)

Overview

The L6561D is a transition mode Power Factor Corrector. It is fully compatible with the standard version, it has a superior performant multiplier making the device capable of working in wide input voltage range applications with an excellent THD. Furthermore the start up current has been reduced at few tens of mA and a disable function has been implemented on the ZCD pin, guaranteeing lower current consumption in standby mode. Realized in mixed BCD technology, the chip gives the benefits micro power start up current 1% precision internal reference voltage soft output over voltage protection, no need for external low pass filter on the current sense very low operating quiescent current minimizes power dissipation. The totem pole output stage is capable of driving a Power MOS or IGBT with source and sink currents of ±400mA.
