8.2.2.4 Rectifier Diode Selection

Both converters (the boost and inverting converter) require rectifier diodes, D1 and D2. As a recommendation, to reduce losses, use Schottky diodes. The forward current rating needed is equal to the maximum output current. Consider that the maximum currents, IPOSmax and INEGmax, might differ for VPOS and VNEG when choosing the diodes.
