Dual Output Inverting Buck-Boost Reference Design Using TPS54060 to Generate +/-31V Output Voltage


Design files


The PMP5653 reference design uses the TPS54060 DC/DC converter to generate dual outputs providing +-31V at up to 70mA. The high-side MOSFET is incorporated inside the TPS54060. The negative output is used as the ground reference for the converter, which allows the regulation of the positive and negative outputs.
