Texas Instruments TPS65296 LPDDR4/LPDDR4X Memory Power IC
Texas Instruments TPS65296 LPDDR4/LPDDR4X Memory Power IC has the lowest total cost and minimizes the required space in a design. It meets the JEDEC standard for LPDDR4/LPDDR4X power-up and power-down sequence requirements. The TPS65296 integrates two synchronous buck converters (VDD1 and VDD2) and a 1.5A LDO (VDDQ). The TPS65296 employs D-CAP3™ mode with 600kHz switching frequency for fast transient, good load/line regulation, and support for ceramic output capacitors without an external compensation circuit.The Texas Instruments TPS65296 provides rich functions and good efficiency with internal low Rdson power MOSFETs. It supports flexible power state control, placing VDDQ at high-Z in S3 and discharging VDD1, VDD2, and VDDQ in S4/S5 state. Full protection features include OVP, UVP, OCP, UVLO, and thermal shutdown protection. 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.
