51216 - TPS51216 - Texas Instruments

DESCRIPTION

The TPS51216 provides a complete power supply for DDR2, DDR3 and DDR3L memory systems in the lowest total cost and minimum space. It integrates asynchronous buck regulator controller (VDDQ) with a 2-A sink/source tracking LDO (VTT) and buffered low noise reference (VTTREF). The TPS51216 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-mF of ceramic capacitance. In addition, a dedicated LDO supply input is available The TPS51216 provides rich useful functions as well v flexible power state control, placing VTT at high-Z in S3 and discharging VDDQ, VTT and VTTREF (soft– off) in S4/S5 state. Programmable OCL with low-side MOSFET RDS(on) sensing, OVP/UVP/UVLO and thermal shutdown protections are also available  TPS51216 is available in a 20-pin, 3 mm × 3 mm, QFN package and is specified for ambient  temperature from –40°C to 85°C.
