4 Revision History

Changes from Revision A (July 2013) to Revision B (April 2021)

  • Added the following sections: ESD Ratings, Feature Description, Device Functional Modes, Force CCM Mode, Application and Implementation, Application Information, Design Requirements, Detailed Design Procedure, Application Curves, Power Supply Recommendations, Layout, Layout Example, Device and Documentation Support, and Mechanical, Packaging, and Orderable Information Go
  • Updated the numbering format for tables, figures, and cross-references throughout the document. Go
  • Updated unique_39_Connect_42_SLVS9322851Equation 2 Go

Changes from Revision May 2012 * () to Revision A (July 2013)

  • Deleted VFBTH - TA = 0°C to 85°C, VO = 1.05 V, continuous mode from the Electrical Characteristics. Go
  • Changed VFBTH - TA = –40°C to 85°C, VO = 1.05 V, continuous mode From: MIN = 751 MAX = 779 mV To: MIN = 754 MAX = 776 mV in the Electrical CharacteristicsGo
  • Changed the Over/Under Voltage Protection section. From: "as the high-side MOSFET driver turns off and the low-side MOSFET turns on" To: "as both the high-side and low-side MOSFET drivers turn off"Go
