Hi, I would like to connect a sensor board to a 12V battery. The sensor board requires two voltages: -3.3V and 5V. I do not want to realize the connection with a so called "virtual ground". I found an interesting double dc/dc converter: http://cds.linear.com/docs/en/datasheet/8471fb.pdf, which would fit my requirements. As a software guy I would prefer a breakout board. Do you know such breakout board? Some other recommendations? Best regards, Felix

Hi Jeff, current is low (under 100mA). Regards, felix
