The TPS65295 device provides a complete power solution for DDR4 memory system with the
lowest total cost and minimum space. It meets the JEDEC standard for DDR4 power-up and power-down
sequence requirement. The TPS65295 integrates two synchronous buck converters (VPP and VDDQ) and a
1-A sink and source tracking LDO (VTT) and a buffered low noise reference (VTTREF). The TPS65295
employs D-CAP3™ mode coupled with 600-kHz switching frequency for
ease-of-use, fast transient, and support for ceramic output capacitors without an external
compensation circuit.
The VTTREF tracks ½ VDDQ within excellent 0.8% accuracy. The VTT, which provides both 1-A
sink and source continual current capabilities, requires only 10-µF of ceramic output capacitor.
The TPS65295 provides rich functions as well as excellent power supply performance. It
supports flexible power state control, placing VTT at high-Z in S3 and discharging VDDQ, VTT, and
VTTREF in S4/S5 state. OVP, UVP, OCP, UVLO and thermal shutdown protections are also available. The
part is available in a thermally enhanced 18-pin HotRod™ VQFN
package and is designed to operate under the –40°C to 125°C junction temperature range.
