The TPS51216-EP 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-EP 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 10-µF of ceramic capacitance. In
addition, a dedicated LDO supply input is
available.
The TPS51216-EP 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.
