LinkSwitch-TNZ

The LinkSwitch-TNZ family of ICs combine power conversion with lossless generation of AC zero crossing signal used typically for system clock and timing functions. Designs using the highly integrated LinkSwitch-TNZ ICs are more flexible than discrete implementations reducing component count by 40% or higher.

Isolated Zero Crossing Detection Circuit

A zero crossing detector is an electronic circuit used to detect the exact moment when the voltage of an alternating current (AC) signal passes through zero volts. In other words, the zero-crossing detection circuit detects when an AC signal voltage changes from positive to negative and vice versa.
