Description

The PMP6807 reference design uses the TPS51216 to generate a low voltage DRR3 power supply. The VDDQ supply is 1.35V and capable of 4A. The VTT supply is generated using a source/sink LDO that is capable of 0.5A. The design also takes advantage of high performance compact MOSFETs (CSD17313Q2) to achieve efficiency over 90% for most of the load range.

Features
  • Provides all the power rails needed for DDR3 LV memory
  • Operates under single cell Lithium-Ion batter (3.0 - 4.2V) input
  • Very compact design saving required PCB area
  • Supports various sleep modes controlled by a controller
  • Great efficiency of over 93%
  • This design is tested and ready to plug into memory devices
