Many engineers prefer to choose a power supply with ample “headroom” – In a worst-case scenario, if the application draws a power of say, 5W, then a 10W power supply will be selected. The rationale behind this is that a certain factor of safety is required for maximum reliability in addition to making sure that if extra features are added to the application circuit in the future, there will be enough spare power supply capacity to cope with any additional load. These are pow...
