  Extending the Input Voltage Range of PowerPath Circuits for Automotive and Industrial Applications &mdash AN107
  PDF, 77 Kb, Archivo publicado: jul 30, 2006
  The voltage range of Linear Technology's PowerPath circuits can be easily extended with just a few components, thus allowing them to meet the needs of virtually all applications. This application note presents solutions for circuits that must withstand large negative voltages, a reverse adapter input for example, and circuits that must withstand large positive inputs, such as automotive load-dump.

  Application Note 107
  July 2006
  Extending the Input Voltage Range of PowerPath
  Circuits for Automotive and Industrial Applications
  Greg Manlove
  INTRODUCTION POWER
  SUPPLY The voltage range of Linear Technology’s PowerPath® circuits can be easily extended with just a few components, thus
  allowing them to meet the needs of virtually all applications.
  This application note presents solutions for circuits that
  must withstand large negative voltages, a reverse adapter
  input for example, and circuits that must withstand large
  positive inputs, such as automotive load-dump.
  EXTENDING THE VOLTAGE RANGE
  Any of Linear’s PowerPath controller circuits can benefit
  from an extended voltage range, even those that already
  have wide operating and absolute maximum voltage
  ranges. For instance, the LTC4412HV and LTC4414 will
  each withstand voltages from –14V to 40V, which can be
  extended further using the techniques described here.
  Likewise, the LTC4412’s range of –14V to 28V can be
  extended. The voltage ranges of monolithic PowerPath
  solutions such as the LTC4411, which ranges from –0.3V
  to 6V, can also be extended, though not as far. …
