TPS51216RUKR Description

Short technical summary and product information.

The TPS51216RUKR from Texas Instruments is designed to provide a comprehensive power supply for DDR2, DDR3, and DDR3L memory systems, optimizing for cost and space. It 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).

This IC employs D-CAP mode with selectable switching frequencies of 300 kHz or 400 kHz for fast transient response and ease of use. The VTTREF accurately tracks VDDQ/2, and the VTT LDO can handle 2-A peak currents, requiring minimal external capacitance. The device supports flexible power state control, including high-Z state in S3 and soft-off in S4/S5 states.

Protection features include programmable Overcurrent Limit (OCL), Overvoltage Protection (OVP), Undervoltage Protection (UVP), and Undervoltage Lockout (UVLO), along with thermal shutdown. The TPS51216RUKR is available in a 20-pin, 3 mm x 3 mm WQFN package and operates over an ambient temperature range of -40°C to 85°C.

Applications include DDR2/DDR3/DDR3L memory power supplies and SSTL_18, SSTL_15, SSTL_135, and HSTL termination.
