  24V, 15A Step-Down Regulator in Sub-1mm Height Package
  Pushes Monolithic Performance Limits
  Stephanie Dai Monolithic switching regulators and switching controllers together dominate the DC/DC
  converter market. Generally, there is little overlap in their respective applications.
  Controller-based solutions are favored for high performance, higher power applications
  where minimal power loss and top thermal performance are priorities. In contrast,
  monolithic regulators are favored in lower power applications where compact size
  is the main requirement. Controllers typically offer more features than monolithic
  solutions, but are at a significant solution-size disadvantage. The light footprint of
  monolithic regulators usually comes at a cost of features and increased power loss,
  and their reliance on integrated MOSFETs places practical limits on power.
  The LTC3613 monolithic regulator
  blurs the line drawn between applications for controllers and monolithic
  regulators by combining a high performance fully featured controller
  with onboard low RDS(ON) MOSFETs.
  FEATURES The LTC3613 can accept an input voltage between 4.5V to 24V and supports
  output voltages between 0.6V to 5.5V. The
  onboard top and bottom MOSFETs feature low RDS(ON), around 7mО© and 5mО©,
  respectively, keeping power dissipation
  low and allowing the LTC3613 to deliver
  up to 15A of adjustable load current.
  The LTC3613 features true remote differential output voltage sensing. This allows
  for accurate regulation of the output …
