IC, L6561D, STMicroelectronics
The L6561D has a performant multiplier making the device capable of working in wide input voltage range applications (from 85 V to 265 V) 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 stand by mode.
Realised in mixed BCD technology, the chip gives the following benefits: micro power start up current 1 % precision internal reference voltage (T j = 25°C) Soft Output Over Voltage Protection no need for external low pass filter on the current sense very low operating quiescent current minimises power dissipation.
