This reference design is a dual-output, isolated fly-buck power module for a single IGBT driver bias using the TPS54308 synchronous buck converter. The converter generates one non-isolated output of +3.3 V with 400-mA current capability and two isolated outputs of +15 V and -8 V with 80-mA current capability from an input voltage range of 9 V to 22 V.
