Abstract

The TPS6290x-Q1 (TPS62903-Q1, TPS62902-Q1, TPS62901-Q1) and TPS6299x-Q1 (TPS62993-Q1, TPS62992-Q1) are the next generation to the TPS621x0A-Q1 (TPS62130A-Q1, TPS62150A-Q1) family of products. This application note goes through in detail the improvements that were made from the previous version to the new and how those changes benefit the designer. Key concepts discussed further:

  • Feature sets contribute to a smaller solution size
  • Increased operating junction temperature
  • Reduced power losses from a lower quiescent current and improved MOSFET RDS(ON)
  • Increased flexibility enabling a wider range of applications
