TPS53219EVM-690 Wide-Input Voltage Eco-mode™, Single, Synchronous, Step-Down Controller


Order now


The TPS53219EVM-690 evaluation module (EVM) uses the TPS53219. The TPS53219 is a small-size, single buck controller with adaptive on-time D-CAP™ mode control. It provides a fixed 1.1-V output at up to 25 A from a 12-V input bus. TPS53219EVM-690 also uses the 5-mm x 6-mm TI power block MOSFET (CSD86350Q5D) for high power density and superior thermal performance. The TPS53219EVM-690 is designed to use a regulated 12-V bus to produce a regulated 1.1-V output at up to 25 A of load current. The TPS53219EVM-690 is designed to demonstrate the TPS53219 in a typical low-voltage application while providing test points to evaluate the performance of the TPS53219.

  • 25-Adc, steady-state output current
  • Support prebias output voltage start-up
  • High efficiency and high power density by using TI power block MOSFET
  • J1 for selectable switching frequency setting
  • J2 for selectable internal voltage servo soft-start
  • J3 for enable function
  • J6 for auto-skip and forced CCM selection
  • Convenient test points for probing critical waveforms
