Looking for step-up dc/dc converter with Vin 2.5V , Vout 30V

Hi Shai,

We have Boost regulator device which has minimum voltage  2.3V but max is 25 V & current up 2A

P.N :-ISL97516/ISL97519A

Else you can check Boost buck controller :- P.N :-ISL85403 

In Boost mode it will work from 2.5V 

Thanks

AB

Shai  shalom you   can use ISL97519A   with extrenal  Fet  for higher  voltage  choose a  fet  with 65-55v at least   see   explanation in the   datasheets make sure you  are  with in  the  chip correct   spec limitation of the chip  & run  ISIM simulation at 500kHz   any  if you have  questions  please call me  shabat shalom  koby

AB_RENESASand koby,

Thanks a lot for your response, ISL97519A indeed looks like a good candidate with cascaded MOSFET topology.

Could you please share any schematic as a reference design to implement this topology correctly for achieving 30V output?

Waiting for your kind feedback, thanks a lot.

Hi Shai, 

You can refer schematic from EVB for normal operation & refer cascaded operation for your spec. 

To get review of your schematic kindly submit a Technical Support ticket by going to our support portal from the following link: https://en-support.renesas.com

You will need to sign in with your company email address, and if you don't have an account you will need to register with one. https://www.renesas.com/register .

Thanks

AB_RENESAS,

Can you please provide me with more detail/explain how this Cascaded MOSFET works?

Maybe there are application notes regarding the Cascaded MOSFET method?

Waiting for your kind feedback, thanks a lot.

Dear AB_RENESAS,

 Thanks a lot for your kind feedback, 

The customer wants a more detailed/explanation of how this Cascaded MOSFET method works.

Maybe there are application notes regarding the Cascaded MOSFET method can you please elaborate more?

Waiting for your kind feedback, thanks a lot, and happy new year :).

KR,

Shai

Hi Shai, 

You can refer details form datasheet & once your schematic done we can review the same .

As there no specific application note available for cascaded MOSFET.

Thanks 

AB
