Description

The TPS65094 device is a single-chip solution, power-management integrated chip (PMIC) designed

specifically for the latest Intel™ processors targeted for tablets, ultrabooks, notebooks, industrial PCs, and

Internet-of-Things (IOT) applications using 2S, 3S, or 4S Li-Ion battery packs (NVDC or non-NVDC power

architectures), as well as wall-powered applications.

The TPS65094 device is used for essential systems with low-voltage rails merged for the smallest

footprint and lowest-cost system-power solution. The TPS65094 device provides the complete power

solution based on the Intel Reference Designs. Six highly efficient step-down voltage regulators (VRs), a

sink or source LDO (VTT), and a load switch are controlled by power-up sequence logic to provide the

proper power rails, sequencing, and protection—including DDR3 and DDR4 memory power. The two

regulators

(BUCK1

and

BUCK2)

support

dynamic

voltage

scaling

(DVS)

for

maximum

efficiency—including support for Connected Standby. The high-frequency VRs use small inductors and

capacitors to achieve a small solution size. An I2C interface allows simple control by an embedded

controller (EC) or by a system on chip (SoC).

The PMIC comes in an 8-mm × 8-mm single-row VQFN package with a thermal pad for good thermal

dissipation and ease of board routing.
