By applying a positive output pulse of the pulse width modulator to the transistor Q1 it gets turned on. An input current in flows through Vin Q1 inductor L and then divides into two parts one flows through capacitor C and other through load.
In this mode inductance stores the energy and induced voltage in inductor bunks the input voltage.
