Many applications that use 110V/230V-ac mains require a ZCD (zero-crossing-detection) circuit for the ac-line voltage, for example, to synchronize the switching of loads. One method of ZCD uses a high ...
The R2A20133D is the active power factor correction controller that operates in the critical conduction mode (CRM). The R2A20133D is the voltage mode CRM, such that the Power MOSFET controlled by this ...
