TPS61260: Inductor size reduction

Victor Chorques Frigols

Part Number: TPS61260

Hello all, I'm on a new design involving a TPS61260DRVR - 4V output and Iout Max 100mA. Recommended inductor is LQM2HPN4R7MG0 which is quite big 2.5mm x 2 mm (1mm tall).

I wanted to reduce inductor's size. My candidates are: DFE201610E-4R7M=P2 and LQM18PN4R7MFRL. Are they suitable for this application?

Thanks in advance,

Víctor

Hi Victor:
May you share the Vin? It's another key for calculation the Ipeak.

And it's better for you to share the detail data of other inductance, or I'm afraid of we are not talking about same inductor.
