1. A system for determining a power requirement for a device, the system comprising:
a buck converter supplying output voltage, the output voltage of the buck converter driven by a Time on (Ton) pulse generator generating Ton pulses to control charging of a load capacitor of the buck converter;
a device coupled to buck converter, the buck converter supplying output voltage to the device and the device having a counter counting Ton pulses during the supply of output voltage; and
a controller coupled to the counter and the buck converter operable to determine the power requirement for the device based on the count of the Ton pulses.
