1.3 Description
The TPS65094x 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 TPS65094x device is used for essential systems
with low-voltage rails merged for the smallest footprint and lowest-cost system-power solution. The
TPS65094x 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.
