The TPS65296 device provides a complete power solution for LPDDR4/LPDDR4X memory system with the lowest total cost and minimum space. It meets the JEDEC standard for LPDDR4/LPDDR4X power-up and power-down sequence requirement. The TPS65296 integrates two synchronous buck converters (VDD1 and VDD2) and a 1.5-A LDO (VDDQ).

The TPS65296 employs D-CAP3™ mode with 600-kHz switching frequency for fast transient, good load/line regulation, and support for ceramic output capacitors without an external compensation circuit.

The TPS65296 provides rich functions as well as 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.
