在一般的嵌入式系統中經常包括許多不同規格需求的電源電路系統。以一個數位相機為例,包含了微處理器,記憶體這些數位元件。這些數位零件只需要降壓型電源供應器,來提供穩定的直流電壓。而控制數位相機鏡頭做伸縮動作的馬達,就需要一個直流轉交流的電源供應器。而相機的液晶顯示器的背光模組所需要的電壓較高。這邊的電源供應器就可能需要升壓型電源供應器。而驅動閃光燈的電壓更需要瞬間數百伏特的電壓。小小一個數位相機系統就需要三到四種不同形式的電源供應器電路。

也因為需要的電源供應器電路種類如此眾多。若以傳統的類比設計方式,當所需的電源電路的規格與需求有所變動。之前的設計就無法輕易重新設計。必須要花很大的工夫重新調整參數。甚至還要再根據新的參數改變整個晶片設計圖。尤其在更換晶片製造的製程時,類比的電源供應器晶片有重新設計上困難。幾乎是要重新製作一個新的晶片。在這一點的比較上數位設計的電源供應器的優勢更是明顯。而且類比的電路架構比起數位電路架構更容易受到外界環境因素變化的影響。舉例來說:工作溫度的變化,元件的老化,比數位電路更容易造成電路特性的漂動
