  Figure 1 shows the complete schematic for a high
  efficiency 12V input to 3.3V output application. The
  compact package contains a low 30mО© RDS(ON)
  synchronous bottom MOSFET switch and a 60mО©
  RDS(ON) synchronous top MOSFET switch for high

  High Efficiency, 15V Rail-to-Rail Output Synchronous
  Step-Down Regulator Can Source or Sink 5A
  Timothy Kozono The LTC3623 is a high efficiency, monolithic synchronous step-down regulator capable of
  sourcing or sinking up to 5A of continuous output current from an input voltage range of
  4V to 15V. Its compact 3mm Г— 5mm QFN package incorporates an abundance of features
  including a low EMI Silent Switcher architecture, output voltage cable drop compensation
  and single resistor output voltage programming. The constant frequency/controlled
  on-time architecture responds quickly to line and load transients even in low duty cycle,
  high frequency applications. The device offers a 400kHz to 4MHz operating frequency
  range with multiple optional protection and monitoring features, enabling compact, robust
  solutions. VIN regulation, discontinuous/continuous mode and a supply current less than
  1ВµA during shutdown make this regulator suitable for a wide range of power applications.
  A single resistor is used to set the internal reference voltage for the device. The
  adjustable internal reference voltage
  sets the output voltage and allows the
  outputВ voltage to operate rail-to-rail,
  from 0V to VIN . The reference voltage
  can be driven directly as an audio
  driver or configured to operate as a
  TEC driver. Capable of sourcing or
  sinking 5A of output current, the regulator moves the output voltage quickly
  in either direction. The output
  current monitor signal can be used …
