TPS61220: Inductor selection

Hi Rodney:

Generally, it's recommended to choose a inductance with Isat>500mA.  What's the Vin and Vout? And the 50mA means load current or input current?

To choose a proper inductance, we need to ensure it has enough value when facing the current spike. Not only considering stable status. The situations like load transient and the startup would take larger current than normal operation.

HI Munqiu

Thanks for the reply.

Vin: 3.2 - 3.7 VDC

Vout: 3.6 VDC

50mA load current (Actually only 20mA). 50mA would be max inrush

Thanks

Rodney
