Description

The TPS650842 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 TPS650842 device is used for essential

systems with low-voltage rails merged for the smallest footprint and lowest-cost system-power solution.

The TPS650842 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), two LDOs, and three load

switches are controlled by power-up sequence logic to provide the proper power rails, sequencing, and

protection—including DDR3 and DDR4 memory power. The three regulators (BUCK1–BUCK3) support

dynamic voltage scaling (DVS) for maximum efficiency—including support for Connected Standby. The

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.
