PMP9194 uses the TPS54020 synchronous-buck SWIFT converter with integrated FETs to provide a 10A/1V solution in less than 22mmx12mm of total board space area. This reference design uses a small 1.1uH inductor, 2x100uF ceramic output capacitors, and small 0402 external components to save space. The device switches at 300kHz and acheives 87% peak efficiency from a 12V input to a 1V output. The TPS54020 is ideal for powering low-voltage, high-current DSPs and FPGAs, and can be synchronized 180 degrees out-of-phase with another TPS54020 to reduce input ripple.

  • 264mm2 total power supply area
  • Only 2x100uF ceramic output caps
  • 87% peak efficiency from 12V input to 1V output
  • Maximum temperature rise on package of only 35degC
  • Only fifteen (15) total power supply components
  • Tighter than 2% load regulation
