Step-up Switching Regulation

The basic step–up switching regulator

Energy is stored in the inductor during the time that transistor
Q1 is in the “on”state. Upon turn–off, the energy is transferred
in series with Vin to the output filter capacitor and load.
This configuration allows the output voltage to be set to any
value greater than that of the input by the following relationship:
Vout = Vin( ton/toff) + Vin
