In this application note, a DC electronic load is used to provide a current load that steps from a low current draw to a higher value in a short period of time. By directly measuring the voltage and current output of the supply with the stepped load, one can visually observe the recovery of the power supply feedback loop and make changes to the design to optimize the response.

Building blocks of modern embedded systems, including processors, SoCs, system DRAM, non-volatile memories, sensors, and connectivity modules, have varied power requirements. On one extreme, a system power management IC (PMIC) integrates all or almost all of the required power rails. On the other hand, individual power rails are implemented using discrete dc/dc and LDOs.
