Description

The TPS51216RUKT is a Complete Memory Power Supply IC that provides a complete power supply for DDR2, DDR3 and DDR3L memory systems in the lowest total cost and minimum space. It integrates a synchronous buck regulator controller (VDDQ). The TPS51216 employs D-CAP™ mode coupled with 300/400kHz 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 10µF of ceramic capacitance. It supports 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.
