  Automotive Environments and Consumes Only 100ВµA of
  Quiescent Current – Design Note 378
  Rich Philpott
  Introduction
  Automobile electronic systems place high demands on
  today’s DC/DC converters. They must be able to precisely
  regulate an output voltage in the face of wide temperature
  and input voltage ranges—including load dump transients
  in excess of 60V and cold crank voltage drops to 4V. The
  converter must also be able to minimize battery drain in
  always-on systems by maintaining high efficiency over a
  broad load current range. Similar demands are made by
  many 48V nonisolated telecom applications, 40V FireWire
  peripherals and battery-powered applications with auto
  plug adaptors. The LT3437’s best in class performance
  meets all of these requirements in a small thermally
  enhanced 3mm Г— 3mm DFN package.
  Features of the LT3437
  The LTВ® 3437 is a 200kHz п¬Ѓxed frequency, 500mA
  monolithic buck switching regulator. Its 3.3V to 80V
  input voltage range makes the LT3437 ideal for harsh
  automotive environments. Micropower bias current and …
