need help, finding a dc/dc converter
my 532mn bench laser is expressing it's desire to be used at camp fires with a scanning line generation. but my problem is the controller -5 g +5 so split rail the DC/DC converters i am finding either need 18 volts to start pr the ones that will run on the 12 volts i need don't have enough current. The 5 volts at one amp for the laser and -5 volts for the TEC control at 1 amp or so, the ones i am running into only start to work at 18 volts, i would rather not need to build a battery to this and am hoping that you guys can help me on this split rail, 5 volts + and - or two 12 in 5 out dc/dc isolated output, if i can get 2 that are isolated i am make it work with 1-2 amp on the current for both rails.
the reason for this is it will be operated in a rural area with no ac, the fire pit is to far from the house
my only other recourse is to build a custom battery using 16850 cells and just liner regulator ic's
