1.3 Description
The TPS650941 device is a single-chip solution, power-management IC designed specifically for the latest
Intel™ processors targeted for tablets, ultrabooks, and notebooks with NVDC or non-NVDC power
architectures, using 2S, 3S, or 4S Li-Ion battery packs. The TPS650941 device is used for essential
systems with low-voltage rails merged for the smallest footprint and lowest-cost system-power solution.
The TPS650941 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–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 QFN package with a thermal pad for good thermal dissipation and ease of
board routing.
