12V 1A Power Supply Circuit Design using VIPer22A 12V 1A Power Supply Circuit Design using VIPer22A

Switched-mode power supply circuits (SMPS) are most often required in many electronic designs to convert the AC mains voltage to a suitable level of DC voltage for the device to operate. This type of AC-DC converter takes in the 230V/110V AC mains voltage as input and converts it to low-level DC voltage by switching it, hence the name switch-mode power supply. We have…

12V/27W SMPS Circuit with UC3843 Design a 12V/27W SMPS Circuit with UC3843 SMPS Controller IC

Switching Mode Power Supply, or simply SMPS, is a type of Power Supply Unit (PSU) that uses a switching device (such as a transistor or MOSFET) to convert the source, which can be AC or DC, to a constant DC voltage. Switched-mode power supply circuits (SMPS) are most often required in many electronic designs to convert the AC mains voltage to a suitable level of DC voltage…
