Dear all,
May I know how do we normally calculate the power consumption or rather current consumption of a circuit design? Do we sum up the maximum supply current of each component on the circuit to estimate the maximum current consumption?
How many percent extra current should we supply for the circuit? For e.g. if a circuit requires 15V@2A, should we only supply it 15V@2A or say, 15V@3A which is 50% extra in terms of supply current.
Thanks,
Eric Mar
