LM25141: About Load capacity

Guru 21045 points
Part Number: LM25141

Hi Team,

 

We would like to use the load capacity of around 500mF at the following conditions.

I guess that inrush current at startup is increased by the load capacity so I concern that LM25141 can't startup.

Is my understanding correct?

Could you please let us know if you have other concern and workaround?

 

[Conditions]

VIN=4.0V to 20V

VOUT=3.8V

IOUT=3A

Fsw=440kHz

L=6.8uH

Cout=22uF x 2

Load capacity is 500mF (ESR is around 35mohm)

 

Regards,

Kanemaru
