Switch-mode regulators include the buck (step-down) and the boost (step-up), forward and flyback topologies, as well as the SEPIC, hysteretic and multiphase converters. Two basic IC topologies are ...

Peter Green explains advantages of LED drivers based on the flyback power-supply topology: They're inexpensive; they provide an isolated output that complies with UL safety requirements; they make it ...

This article presents basic principles and functions of standard flyback converters as well as its advantages, uses and complex architecture variations. It also explains how to make design choices for ...

The single stage PFC flyback converter remains the topology of choice in many off line AC-DC LED power supplies. This is largely due to its low component count and cost, combined with efficiency of ...
