ZXLD1374
Document number: DS35032 Rev. 2 - 2
Applications Information
For example, in a Buck configuration (V
400 kHz, the Ideal inductor size is L= 33µH.
The same kind of graphs can be used to select the right inductor for a Buck configuration and a LED current of 750mA, as
shown in figures 34 and 35.
