TPS543C20 2-Phase, 80A Synchronous Step-Down SWIFT™ Converter Evaluation Module


Order now


The TPS543C20EVM-869 is a two-phase buck converter with two TPS543C20 devices interleaved. It uses a nominal 12-V bus to produce a regulated 0.9-V output at up to 80-A load current (40-A per phase). The TPS543C20EVM-869 is designed to demonstrate the stacking operation of the TPS543C20. The TPS543C20EVM-869 can be modified into two separate single-phase buck converters by changing the components assembled.

  • 500-kHz operation
  • 10-mVpp ripple at 40 A
  • Module supports 5-V to 16-V input
