20-W, 2-switch buck boost reference design with variable output voltage

This reference design uses the LM25118-Q1. The input voltage is between 9 V and 16 V (withstanding pulse to 32 V). The output voltage is variable from 2 V to 18 V by means of a DAC control input. If the DAC control input is left open, the output voltage is about 13.26 V. With shorted DAC control (...)
