I am having a very hard time looking for a suitable Adjustable Voltage Regulator that can supply from 1V to 4V DC with 15A.
I found some but:
- If it can go to 15A, then the lowest voltage it cannot get to 1V (even not to 2V)
- If it can go to 1V, then the maximum current it can get is 5A
- If it can go to 1V + 15A then it is not adjustable

I googled, searched on Digikey, ebay, National Semiconductor, Analog Devices but no luck.

I am very much appreciated for any suggestion

 

have a look here. It has a selection panel for your min and max input and desired output and amperage.

I looked for two hours but still unable to find one that has the voltage adjustable from 1 to 4V with 15A.

I found LTC3834-1 claimed to have 15A but I cannot find that maximum output current in the specs.

 

Hello,

Take a look at this one:

For low V and high I, DC to DC converters are more efficient.
