Boost converter dual polarity

[engr_joni_ee]

Hi,

I am looking for commercial boost converter. Input voltage is 2.75 V. The maximum input current is up to 5 A. At the output I need both +5 V and -5 V. The load current requirement is 1.5 A. Any suggestion ?

You must specify cost, qty, ripple, efficiency , size , Vin min:max
OR purpose

Raw math says you plan to input 13.75 W max. This is beneath your loads expected 15 W. Can you revise your specs?

Another question: Do you need genuine bipolar supply rails (positive & negative). In other words do you need for the negative supply rail to pull (sink) current?
