TPS51116RGET

The Texas Instruments TPS51116RGET is a versatile power management IC designed as a complete solution for DDR, DDR2, DDR3, DDR3L, LPDDR3, and DDR4 memory.

This device integrates a synchronous buck controller for VDDQ and a 3A LDO for VTT, along with a buffered reference (VREF). It offers a wide input voltage range from 3.0V to 28V, making it suitable for various applications. Key features include D-CAP mode with a 100-ns load step response, support for ceramic output capacitors, and options for current sensing. The output voltage is adjustable, supporting DDR memory requirements from 2.5V down to 1.2V or a general output range of 0.75V to 3.0V.

The TPS51116RGET is available in a 24-VQFN (4x4 mm) package and operates within a temperature range of -40°C to 85°C. It includes essential protection features such as Powergood, Overvoltage Protection, and Undervoltage Protection, along with thermal shutdown for enhanced reliability. The LDO is capable of sinking and sourcing 3A, and the VREF output has an accuracy of ±20 mV.

This component is ideal for systems requiring efficient and stable power delivery to DDR memory modules, ensuring optimal performance and reliability in demanding applications.
