TPS63036: About the inductance value in Light load.

Kengo.Y

Part Number: TPS63036

Hi team,

I'd like to know how to calculate the inductance value in the light load.
My customer usually uses 70mA load.

Condition
Vin : TBD (4V~1.5V)
Vout : 3.3V
Iout(MAX) : 70mA

At this time, how about capacitance value?

Sincerely.
Kengo.

Hi Kengo,

for such condition, you can just select typical inductance 1.5uF. capacitor could be 30uF nominal value

Hi Jasper,

Thank you for your reply.
Could you tell me how to select the inductor and capacitor in our conditions?
I would like to know if there is no problem with that choice.

Sincerely.
Kengo.

Hi Kengo,

I would suggest to select the typical value recommended in the datasheet, 1.5uH for inductor and 30uF nominal for capacitor. these value is designed for 0A to full load. the value cover your application condition.
