LP8556: Inductor selection

Part Number: LP8556

Hello,

My customer use LP8556 the bellow condition.

Vin : 8.1 ~ 13.2

Vout : 30V (8S6P)

Iout : 120mA (20mA / ch)

Fsw : 1250kHz

We see '9.2.2.1 Recommended Inductance for the Boost Power Stage ' in datasheets,

they wish choose inductance value of 10 μH - 22 μH. 

They hope to use inductance value of  4.7uH, because they want to size down. 

Is there a way to use this value?

Regards,

Taichi Nakamura
