  Design Once; Use Twice: Monolithic SEPIC/Boost Regulators
  with Wide VIN Range Satisfy Requirements of Both Consumer
  and Commercial Vehicles
  Molly Zhu Automobile manufacturers continually add electronic control units (ECUs) to support
  increasing numbers of performance, comfort and safety features. ECU power either
  comes from a single lead-acid battery in consumer vehicles, or from two batteries in
  commercial vehicles. Ideally, an ECU can run off either, enabling a single design for
  both consumer and commercial vehicles. This requires that ECU power ICs support
  an input range covering both configurations—namely 3.5V to 60V. Furthermore,
  the power ICs should feature ultralow quiescent current, preserving the vehicle’s
  battery run time when the engine is off, but always-on systems remain engaged.
  The LT8495 and LT8494 are high voltage
  switching regulators that meet these
  requirements when configured as
  SEPIC or boost converters. Both parts
  operate over 2.5V to 60V input, and
  have low quiescent current to extend
  the battery life. The quiescent current
  of the LT8495 is 9Вµ A, and is 7Вµ A for the
  LT8494. The parts are available in 20-lead
  QFN and 20-lead TSSOP packages. supply voltage is monitored by poweron reset, and the software/hardware
  activities are supervised by watchdog
  timers. These functions are integrated …
