Buck Boost Converter Circuit Diagram. The buck boost stage consists of a mosfet which acts like a switch the inductor which is the main power converting component the diode. The buck boost converter is a type of dc to dc converter that has an output voltage magnitude that is either greater than or less than the input voltage magn.
L1 can be a toroid potcore or shielded bobbin inductor. If the gate terminal of the first transistor is more than the current pass through the magnetic field charging c and it supplies the load. A typical buck boost converter is shown below.
Input voltage can be between 2 7 to 4 2v.
It can be seen from the diagram that it is a simply the connection of buck converters in parallel. The input voltage source is connected to a solid state device. As shown in the circuit diagram below click to enlarge the configuration is basically a combination of two distinct stages viz the upper buck boost converter stage and the lower ic 555 pwm controller stage.
