9 Revision History

Changes from Revision E (September 2013) to Revision F (January 2024)

  • Updated the numbering format for tables, figures, and cross-references throughout the documentGo
  • Updated to new format which does not include specific parameter names and does include min and max columns.  TJ called out in header.  Pin names are used rather than signal names.  BOOT and PH voltages now marked as output voltage.  Footnotes updated and Note 2 removed.Go
  • Changed BOOT to PH Absolute Maximum to 6 V maximumGo
  • Deleted Absolute Maximum BOOT to GND maximum voltageGo
  • Added ESD tableGo
  • Added Recommended operating VI input voltageGo
  • Updated footnotes to match current TI standards, replaced custom board specifications with EVM information and JEDEC standard information.Go
  • Changed RθJC(top), RθJB, ψJT, ψJB Go
  • Added condition for typical specifications EC table’s header, added parameter names, and used pin names in parameter descriptions.  Footnote added.Go
  • Updated the following test conditions: VFB, DMAX, and RDSON(HS).Go
  • Updated the following typical specifications in the EC table: IQ(VIN), ISD(VIN), VINUVLO(H), VEN(H), and RDSON(HS).Go

Changes from Revision D (January 2013) to Revision E (September 2013)

  • Deleted SWIFT from the data sheet Title, Features, and DescriptionGo
  • Deleted Feature "For SWIFT Documentation"Go
  • Deleted text "As a member of the SWIFT™ family of DC/DC regulators"Go

Changes from Revision C (October 2007) to Revision D (January 2013)

  • Replaced the DISSIPATION RATINGS with the THERMAL INFORMATION tableGo
