nrf52832-DCDC inductor component choice

[WrightLin.Avnet]

Hi, Great Nordic Support teams:

I'm wondering if the only limitation of the choice of L3 on nrf52832 layout is just the tolerance under 10%?

Cause it seems to be the only limitation specific defined by spec. 

And If tolerance is the only limitation, It should be fine to use this Component, right?

(We especially care about DCR and current limitations.)

Thanks for your help.

Hi,

 

The main limitation is inductance and tolerance, yes. The DCR will affect the efficiency of the DCDC converter, and at a couple ohms might even inhibit operation, so you would want to keep it as low as possible. The component you link to should be fine though.

 

Best regards,

Andreas
