Power Stage Design

There are many different circuit topologies used for power conversion and the best one to use depends on your target performance, solution size and most importantly cost. This section gives an outline of the most common topologies which we use on a day-to-day basis. In the diagrams below, only the generic power stage is shown with the active semiconductor switch represented by a simple switch.

Buck Converter
Buck Converter – Vout is Less than Vin

Boost Converter
Boost Converter – Vout is Greater than Vin

Flyback Converter
Flyback Converter – Vout can be higher or lower than Vin

Forward Converter
Forward Converter – Vout can be higher or lower than Vin

SEPIC Converter
SEPIC Converter – Vout can be higher or lower than Vin
