Synchronous Buck Controller (VDDQ)  
The TPS51216 provides a complete power supply for  
DDR2, DDR3 and DDR3L 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 TPS51216 employs  
D-CAP™ mode coupled with 300 kHz/400 kHz  
frequencies for ease-of-use and fast transient  
response. The VTTREF tracks VDDQ/2 within  
excellent 0.8% accuracy. The VTT, which provides 2-  
A sink/source peak current capabilities, requires only

Powergood Output  
The TPS51216 provides rich useful functions as well  
as excellent power supply performance. It supports  
flexible power state control, placing VTT at high-Z in  
S3 and discharging VDDQ, VTT and VTTREF (soft-  
off) in S4/S5 state. Programmable OCL with low-side  
MOSFET RDS(on) sensing, OVP/UVP/UVLO and  
thermal shutdown protections are also available.
