Mode 1

In this mode  transistor Q gets turned on by the positive output  of the PWM. After  that current  flows  through  inductor L  transistor Q then back  to supply  in this  condition inductance stores  the energy.

Assuming that  inductor current rises  linearly from I1  to I2  in time period t1= T on .

 V in = L  I2- I1 / Ton = LI /Ton
