  Features 

This IC outputs the AC voltage zero cross timing detection 

with high accuracy. 

By eliminating the need for opto-coupler and external 

components required in conventional applications, it is 

possible to reduce the number of parts drastically and realize 

compact and highly reliable power supply applications. In 

addition, this IC can reduce standby power largely in 

comparison with an existing opto-coupler control.
