Information – The electrical design for the power supply must ensure
a peak current output of at least 2A.
General Design Rules
The principal guidelines for the Power Supply Design embrace three different design
steps:
 Electrical design
 Thermal design
 PCB layout
4.3.1. Electrical Design Guidelines
The electrical design of the power supply strongly depends on the power source from
which power is drained.
