The PMP21064 reference design is designed using the TPS544B20 for a 15A point-of-load converter in a tiny 0.575"x0.85" solution size (14.6mmx21.6mm). TPS544B20 fully integrates a 20A buck regulator into a small 5mmx7mm QFN package. It features DCAP2 featuring fast dynamic response and is equipped with PMBus capability. The PMP21064 has a size-optimized layout. It is a tiny 15A building block with high efficiency, fast dynamic response and ideal for design reuse.

  • 7V to 14V in, 1V/15A out
  • Full load efficiency 86.3% at 12Vin, 300kHz
  • Fast dynamic transient response +1.1% with 25% load step
  • Total solution size: 0.575" x 0.85" (14.6mm x 21.6mm)
  • Size optimized for design reuse
  • PMBus enabled margining and sequencing
