Question, an accuracy of i.MX28 Internal DC/DC

[SLICE]

Dear team,

According to i.MX28 datasheet, the accuracy of its internal DC/DC is +-3% when there is no load.

Do you have any accuracy data of DC/DC of when there are loads?

My customer is using i.MX28 and they found the accuracy (when there are loads) got lower than the mention of datasheet.

Thanks,

Miyamoto

The typical accuracy of the i.MX28 DC/DC converter under normal load conditions (as specified in the datasheet) and specified external components, i.e. 15uH inductor and at least 33uF of bulk capacitance (typical configuration is 22uF + 10uF + 1uF + 0.1uF + 0.01uF low ESR capacitors in parallel), is +/- 5% .

Have a great day,
Artur
