Hi GARAM,

Buck circuit has the inductor that resists change in the current. If you applied a certain load to the device inductor maintain the current constant and that's the reason to drop in the voltage.

Buck operation is explained in this app note: http://www.ti.com/lit/an/slva057/slva057.pdf

Best regards,

Tanvee
