TI TPS51716RUKR

控制器，DDR3V ~ 28V0.7V ~ 1.8V

Overview

The TPS51716RUKR provides a complete power supply for DDR2, DDR3, DDR3L, and LPDDR3 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 TPS51716RUKR employs D-CAP2™ mode coupled with 500 kHz or 670 kHz operating frequencies that supports ceramic output capacitors without an external compensation circuit. The VTTREF tracks VDDQ/2 with excellent 0.8% accuracy. The VTT, which provides 2-A sink/source peak current capabilities, requires only 10-μF of ceramic capacitance. In addition, the device features a dedicated LDO supply input.
