Description
General part information
TPS51916 Series
The TPS51916 device provides a complete 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 D-CAP2™ mode coupled with higher 500 kHz or 670 kHz frequencies to support ceramic output capacitor without an external compensation circuit. The VTTREF tracks VDDQ/2 within excellent 0.8% accuracy. The VTT, which provides 2-A sink and 2-A source peak current capabilities, requires only 10-µF of ceramic capacitance. A dedicated LDO supply input is available.
The device also provides 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 or S5 state. Programmable OCL with low-side MOSFET RDS(on)sensing, OVP, UVP, UVLO and thermal shutdown protections are also available.
