How to Estimate Static and Dynamic Current Consumption of a Printed Circuit Board?
When designing circuits Often the hardware engineer need to know the current consumption of the printed circuit board being designed. Current consumption is an important parameter to determine the type of power supply solution and the power rating of the components. Secondly it is used to determine the power trace width When doing PCB layout design. More importantly if the board is to be powered by battery, current consumption data is crucial to estimate battery life.
The link below have a good analysis of consumption for the whole board and components and an efficient way to analyze using a DSO.
