8-14V Vin, 1.2V Vout Sync Buck Controller Evaluation Module with NexFET™ Power MOSFETs


Order now


The TPS40304EVM-353 evaluation module is a synchronous buck controller providing a 1.2-V output at up to 20 A from a nominal 12-V input bus. The EVM is designed to start-up from a single supply, and no additional bias voltage is required. The module uses TI’s NexFET™ high performance MOSFETs for high power density and efficiency.

  • 600-kHz operation
  • Uses CSD16410 high-side and CSD16321 low-side MOSFETs
  • Module supports 8-V to 14-V input
