For given design conditions such as ambient temperature, derating requirement, thermal solution, ​

space constraint, cost target, and so on, the aim of power supply design can be categorized into two ​

main areas:​

1. To sustain continuous (DC) current (EDPc) with the target efficiency and thermal performance.​
2. To achieve a target output voltage overshoot/undershoot spec (or generally referred to noise or ​peak-to-peak noise spec) under a specified large load transient event (EDPp​).
