50V 2.5A Output Boost Regulators?

I am trying to find a boost converter that can take a lithium battery bank (3.6-4.5V) and boost it to 50V at a max current of 2.5 amps. Assuming we have the source capacity, do you offer anything boost converters that could accommodate this? If not with a source voltage that low, how about around 9V-14V input?

thanks,

Nick

    Hello,

    when powered with LiIon battery your app asks for an awful lot of current (125W Pout). This will demand for a current from the source in the range of 40A. In this input voltage range we have some non synchronous boost converter like LT3757A, but I would go with your higher input voltage range to ease part selection,  increase efficiency and ease overall design.

    LTC3769 will start from 4,5V onwards and feels very comfortable with the  9-14V input range.

    kind regards
