Key Document


The TPS543C20 is a highly integrated, synchronous buck converter tailored for high density power solutions wich features high performance integrated MOSFETs with very low RDSon to achieve high efficiency. This converter enables the design of a 1V, 20A power supply capable of acheiving efficiency >88% at full load. The differentially enhanced control loop requires no external compensation, reducing the number of components necessary for optimal performance. 

  • Integrated power stage using NexFET technology with very low RDSon, >88% efficiency at 20A load current
  • Selectable voltage reference and programmable switchinig frequency allowing for great design flexibility
  • Differentially enhanced control loop requiring no external compensation
  • Temperature rise < 17o at full load, no forced air
  • Total solution size < 35cm2
