PMP3130 uses the TPS51116 to generate a DDR3 supply for VDDQ and VTT. The VDDQ supply is generated from single cell lithium ion battery to 1.5V at 4A using a synchronous buck converter. The VTT supply is generated using a LDO from 1.5V to 0.75V at up to 3A load current. The TPS51116 is designed to operate in low power skip mode to keep light load efficiency high for portable applications.
