Description

The PMP20026 reference design provides an efficient low power solution for DDR4 memory.  The power supply is powered from a 12V source and regulates the output to 1.2V at up to 6A.  The TPS53515 operates in a single phase buck mode at 500kHz that allows for very high efficiency conversion.  The solution size is25mm x 15mm.  The peak effciency approaches 90% at 5A.  At very light loads the efficiency is still above 40%.

Features
  • 12VIN to 1.2VOUT at 6A
  • Peak efficiency ~89%
  • DCAP3 Mode for Fast Transient Response
  • Bandwidth >100kHz
  • Load Regulation <2%
