・General Description
Features
This IC outputs the AC voltage zero cross timing detection
and the DC voltage after diode rectification 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.
