TPS51216 DDR Memory Power Solution

Texas Instruments TPS51216 DDR Memory Power Solution provides a complete power supply for DDR2, DDR3, and DDR3L memory systems with minimum space. This TI device integrates a synchronous buck regulator controller (VDDQ) with a 2A sink/source tracking LDO (VTT) and buffered low noise reference (V_TTREF). The TPS51216 employs D-CAP™ mode coupled with 300kHz/400kHz frequencies for ease of use and fast transient response. The V_TTREF tracks VDDQ/2 with excellent 0.8% accuracy. The VTT, which provides 2-A sink/source peak current capabilities, requires only 10μF of ceramic capacitance. TPS51216 provides rich, useful functions as well as excellent power supply performance.
