Hi, all guys:
I need to design a high efficiency dc-dc converter for mp3 player application. I sort some dc-dc converter from on-semi or maxim website.
such as ncp1410 or max1706. the efficiency parameter in the datasheet is
very high(95%) . but in my actual application , the Vin=1.5v , Vout=2.7V the coil value is 33uH(coilcraft power inductor). the efficiency is just 78%.
why is there so large difference between them . ?
