nPM1300 vout1 inductor

[Poki Huang]

Hi

I have questions about nPM1300 VOUT1 inductor

1. Our load current for VOUT1 will be <20mA, so could we use below inductor?

2. Datasheet 6.3.5 define it's recommended DCR value is <400mohm, if >400mohm, except more power consumption, any other side effect? 

Thank you

Hi Poki,

If the current draw is low then it should be OK to use a inductor with DCR of 700 mOhm

Hi Bendik:

By above <20mA load current condition

Can we use below 1uH inductor?

Thank you

Hi Poki,

The VOUT inductor must be 2.2uH, so this 1uH can not be used.
