Two different topologies are called buck boost converter both of them can produce a range of output voltages ranging from much larger.

Vin vout ton vout toff where vin is the input voltage to upper mosfet drain vout is the output voltage ton is the on time of the up per mosfet and toff is the off time of the upper mosfet. V o is the output voltage.
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 magnitude.
An application of this is in a maximum power point tracker commonly used in photovoltaic systems. By the equation for electric power. Core losses of an indicator in buck converter are mainly affected by three factors i e. V o is the output voltage.
