LM25145: LM25145

Part Number: LM25145

Hello,

I'd like to ask to what extend can I increase inductor ripple current using LM25145?

Could it be up to 100%? 150%?

I'm asking only about stability issues - whether this regulator can work in high DCM mode, switch between CCM, DCM whil load is changing?

Because this is voltage-mode controled chip, right?

Not asking in terms of Out Cap ESR or Inductor power.

Regards,

Adam

I simulate in the wenbench tools for large current ripple.

it is OK.

attached is the waveform for 5V10A output

Thanks,

but in not DCM condition, I see DC current is 5A, I'm interesting what will happen when DC load current will be like 1A, and not only intersted in steady state conditions but also during load switching.

But I'll try with webench
