Buck inductor calculation
Webelectronic devices. As a result, Bourns has developed several inductor models with rated DC current up to 60 A to meet the challenges of the market. Especially given the myriad of choices for inductors currently available, properly selecting an inductor for a power converter is not always a simple task for designers of next-generation applications. WebFor typical buck power supply designs, the inductor's ripple current, ΔI, is less than 30% of the total output ... The following example shows how to calculate a power supply's efficiency at any output voltage if the power supply's efficiency is known at any other output voltage. This method of computing efficiency
