1.3 Description
The TPS650932 device is a single-chip solution, power-management IC (PMIC) designed specifically for
the latest Intel Cannon Lake processors targeted for tablets, ultrabooks, and notebooks with NVDC or
non-NVDC power architectures, using 2S, 3S, or 4S Lithium-Ion battery packs. The device can provide a
power solution based on Intel Reference Designs.
Five highly-efficient step-down voltage regulators (VRs) and a sink-source LDO are used along with
power-up sequence logic managing external load switches to provide the proper power rails, sequencing,
and protection—including DDR3 and DDR4 memory power. The regulators support dynamic voltage
scaling (DVS) for maximum efficiency including connected standby. The high-frequency voltage regulators
use small inductors and capacitors to achieve a small solution size. Output power is adjustable on the
controllers to scale across processor skews and applications. An I²C interface allows simple control by the
embedded controller (EC).
The device is available in a 7×7 nFBGA package (ZAJ). The ZAJ package can be used in Type-4 PCB
boards for the smallest area implementation.
