TPS51916 Description
The TPS51916 device provides a plete power supply for DDR2, DDR3, DDR3L, and DDR4 memory systems in the lowest total cost and minimum space. It integrates a synchronous buck regulator controller (VDDQ) with a 2-A sink and 2-A source tracking LDO (VTT) and buffered low noise reference (VTTREF). The device employs D-CAP™ mode coupled with 300 kHz or 400 kHz frequencies for ease-of-use and fast transient response or...
