TPS546D24S - Step-Down Converter

General Description

The TPS546D24S is a highly integrated, non-isolated DC/DC converter that expands on the TPS546D24A by adding manufacturer-specific PMBus commands and Extended Write Protect and Passkey.

Key Features

  • Integrated extended security feature.
  • Split rail support: 2.95-V to 16-V PVIN; 2.95-V to 18-V AVIN (4-VIN VDD5 for switching).
  • Integrated 4.5-mΩ/0.9-mΩ MOSFETs.
  • Average current mode control with selectable internal compensation.
  • 2 ×, 3 ×, 4 × stackable with current sharing up to 160 A, supporting a single address per output.
  • Selectable 0.5-V to 5.5-V output through pin strap or 0.25-V to 5.5-V using PMBus VOUT_COMMAND.
  • Extensive PMB.
