TPS61023: Inductor value design

Hello,

if I need 1.5A rated output current,  how much inductor saturation current at least?

Thanks.

Hi Chambin,

Please read datasheet 8.2.2.2 Inductor Selection for guidance.

Hi Travis,

if I need 1.5A rated output current,  how much inductor saturation current and DC current at least?

Thanks

Hi Chambin,

That depends on your Vin and Vout.

Hi Travis,

Our input range is 2.3-3.3V, Output voltage is 5V/1.5A .

Could you recommend proper inductor parameters?

Thanks.

Hi Chambin,

The critical value is around 4.2A. So I recommend 5A for some margin.

Best Regards,

Travis

Hi Travis,

Thanks for your support.

Could you tell me which current 4.2A belong to? saturation current and DC current of inductor?

Could you tell how to calculate this current or tool can be used for calculation?

Thanks.
