  Monolithic Buck Regulator with
  Built-In DAC and I2C Interface by Earl Barber
  Introduction Minimal Space
  Figures 1 and 2 show the LTC3447
  powered from a single Lithium-Ion
  battery. To minimize critical board
  real estate, only two ceramic capacitors, a single inductor, and a single
  resistor are required for operation.
