  Jim Williams and Todd Owen boost. It differs from the typical
  LTC1775 buck converter applications
  in several important ways. First, the
  LTC1775 is connected between the
  positive input voltage and the negative output voltage with the output of
  the inductor connected to the system
  ground. Thus, the LTC1775 and the
  power MOSFET switches are exposed
  to a voltage that is the sum of VIN +
  |VOUT|, which must be kept below …
