Buck Boost Converter Circuit Diagram. 3 3 2 to 3 3 5 fig. It can be seen from the diagram that it is a simply the connection of buck converters in parallel.
L1 can be a toroid potcore or shielded bobbin inductor. Assemble the circuit on a good quality pcb. In the buck converter first transistor is turned on and second transistor is switched off due to high square wave frequency.
In the buck converter first transistor is turned on and second transistor is switched off due to high square wave frequency.
3 3 2 shows the circuit operating as a buck converter. 3 3 2 shows the circuit operating as a buck converter. The inductor l and capacitor c constitute the efficient output filtering. The power switch q1 is an n channel mosfet.
