TPS51716RUKR DDR Voltage Regulator IC 3 Output 20-WQFN
The TPS51716RUKR, manufactured by Texas Instruments, is a highly integrated synchronous buck controller designed to provide a complete power management solution for DDR2, DDR3, DDR3L, LPDDR3, and DDR4 memory systems. This advanced PMIC integrates three essential functions into a single 20-WQFN package with an exposed thermal pad: a synchronous buck controller for the VDDQ supply, a 2-A sink/source tracking low-dropout linear regulator (LDO) for the VTT termination rail, and a low-noise buffered reference voltage output (VTTREF) that tracks half of VDDQ. Operating from a wide input voltage range of 3 V to 28 V, the device delivers an adjustable output voltage from 0.7 V to 1.8 V and is specified for the industrial temperature range of –40°C to +85°C.
The TPS51716RUKR is ideally suited for a broad spectrum of computing and networking applications requiring complete DDR memory power solutions. In laptops, desktops, workstations, and servers, the device provides the core VDDQ, VTT, and VTTREF rails necessary to power DDR2, DDR3, DDR3L, LPDDR3, and DDR4 memory modules. The high level of integration and compact WQFN package make it particularly valuable for space-constrained designs such as ultrabooks and mini-PCs. In networking equipment, the TPS51716RUKR serves in routers, switches, and base stations, where reliable memory power is essential for high-speed data processing. Additional applications include industrial automation, data storage systems, renewable energy systems, automotive infotainment, and telecommunications infrastructure.
