TI TPS650940A0RSKR

The TPS65094 device is a single-chip solution power management integrated circuit (PMIC) designed specifically for the latest Intel processors. These processors target tablets, Ultrabooks, notebooks, industrial computers, and Internet of Things (IoT) applications powered by 2-cell, 3-cell, or 4-cell lithium-ion battery packs (NVDC or non-NVDC power architectures), as well as wall-powered applications. The TPS65094 device is used to combine the necessary systems for low-voltage rails to achieve the smallest size and lowest-cost system power solution. The TPS65094 device can provide a complete power solution based on the Intel reference design. Six high-efficiency buck voltage regulators (VRs), a sink/source LDO (VTT), and a load switch are controlled by the power-up sequence logic to provide the correct power rails, sequencing, and protection - including DDR3 and DDR4 memory power. Two voltage regulators (BUCK1 and BUCK2) support dynamic voltage scaling (DVS) to maximize efficiency (including support for the connected standby function). The high-frequency VRs use small inductors and capacitors to reduce the solution size. With the I2C interface, the control functions can be easily implemented through an embedded controller (EC) or system-on-chip (SoC). The PMIC is packaged in an 8mm×8mm single-row VQFN package with a thermal pad, providing good thermal performance and simple board routing.
