Synchronous Buck Controller (VDDQ)  
–
–
Wide-Input Voltage Range: 3.0-V to 28-V  
The TPS51116 provides a complete power supply for  
DDR/SSTL-2, DDR2/SSTL-18, and DDR3 memory  
systems. It integrates a synchronous buck controller  
with a 3-A sink/source tracking linear regulator and  
buffered low noise reference. The TPS51116 offers  
the lowest total solution cost in systems where space

a premium. The TPS51116 synchronous

–
Supports Soft-Off in S4/S5 States  
controller runs fixed 400kHz pseudo-constant  
frequency PWM with an adaptive on-time control that  
can be configured in D-CAP™ Mode for ease of use  
and fastest transient response or in current mode to  
support ceramic output capacitors. The 3-A  
sink/source LDO maintains fast transient response  
only requiring 20-µF (2 × 10 µF) of ceramic output  
capacitance. In addition, the LDO supply input is  
available externally to significantly reduce the total  
power losses. The TPS51116 supports all of the  
sleep state controls placing VTT at high-Z in S3  
(suspend to RAM) and discharging VDDQ, VTT and  
VTTREF (soft-off) in S4/S5 (suspend to disk).  
TPS51116 has all of the protection features including  
thermal shutdown and is offered in both a 20-pin  
HTSSOP PowerPAD™ package and 24-pin 4

 QFN.  
Current Sensing from RDS(on) or Resistor
