Application Scenarios & Design Considerations

30-V, 500-mA Switch Boost Converter in QFN-8 for White LED Applications 8-SON -40 to 85

Alternative Part Number

  • TPS61040DBVR --: Same TPS6104x boost converter family in SOT-23-5 package; similar boost topology and control, suitable when the DRB package is not required.
  • TPS61041DBVR --: Sister boost converter in the TPS6104x series with comparable input range and switching behavior, available in a smaller SOT-23 package.
  • AP3012KTR-G1 --: Alternative boost converter from a different vendor with similar step-up function and compact package, useful as a second-source option.
  • TPS61042DRBR --: Same TPS61042 boost converter in the same SON-8 package, identical electrical specifications; the RG4 suffix only denotes a lead-free/Green ordering variant, so this is a drop-in replacement.
  • TPS61041DRBR --: Same TPS6104x family boost converter with nearly identical topology and pinout in SON-8; check the current-limit and feedback threshold differences before substituting.
  • TPS61040DRBR --: Closely related TPS6104x boost converter in the same SON-8 package with similar functionality; verify output current and switching frequency against the original design.
