TPS546D24A - Buck Converter

General Description

The TPS546D24A is a highly integrated, non-isolated DC/DC converter capable of high frequency operation and 40-A current output from a 7-mm × 5-mm package.

Two, three, and four TPS546D24A devices can be interconnected to provide up to 160 A on a single output.

Key Features

  • 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 via pin strap or 0.25-V to 5.5-V using PMBus VOUT_COMMAND.
  • Extensive PMBus command set with telemetry for VOUT, IOUT and inter.
