The TPS51216RUKR from Texas Instruments is designed to provide a comprehensive power solution for DDR2, DDR3, and DDR3L memory. This integrated circuit features a synchronous buck controller for VDDQ and a 2-A sink/source tracking LDO for VTT, along with a low-noise buffered reference (VTTREF).
It operates with an input voltage range of 3 V to 28 V and an output voltage range of 0.7 V to 1.8 V. The device utilizes D-CAP mode for fast transient response and offers selectable switching frequencies of 300 kHz or 400 kHz. The VTTREF tracks VDDQ/2 with 0.8% accuracy, and the VTT LDO provides 2-A peak current capabilities.
Protections include Overcurrent Limit (OCL), Overvoltage Protection (OVP), Undervoltage Protection (UVP), and Undervoltage Lockout (UVLO), along with thermal shutdown. The TPS51216RUKR supports flexible power state control, including high-Z in S3 and soft-off in S4/S5 states. It is available in a 20-pin, 3 mm x 3 mm QFN package and operates over an ambient temperature range of -40°C to 85°C.
This component is suitable for DDR2/DDR3/DDR3L memory power supplies and SSTL_18, SSTL_15, SSTL_135, and HSTL termination applications.
