Description

The PMP20025 reference design provides a compact low power solution for DDR4 memory.  The power supply is powered from a 12V source and regualtes the output to 1.2V at up to 6A.  The TPS62180 operates in a two phase buck mode that allows for very small external components.  The solution size is 10mm x 15mm.  The effciency at close to full load is approximately 80%.  At very light loads the efficiency is still above 50%.

Features
  • 12VIN to 1.2VOUT at 6A
  • Small Solution Size 10mm x 15mm
  • Max Height 1.2mm
  • Light Load Efficiency for Improved No Load Performance
  • Out of Phase Operation for Ripple Current Cancellation
