FEATURES  
DESCRIPTION  
The TPS51716 provides a complete power supply for  
DDR2, DDR3, DDR3L, and LPDDR3 memory  
systems in the lowest total cost and minimum space.  
It integrates a synchronous buck regulator controller  
(VDDQ) with a 2-A sink/source tracking LDO (VTT)  
and buffered low noise reference (VTTREF). The  
TPS51716 employs D-CAP2™ mode coupled with  
500 kHz or 670 kHz operating frequencies that  
supports ceramic output capacitors without an  
external compensation circuit. The VTTREF tracks  
VDDQ/2 with excellent 0.8% accuracy. The VTT,  
which provides 2-A sink/source peak current  
capabilities, requires only 10-μF of ceramic
