1.3 Description
The TPS650830 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 Lithium-Ion battery packs.
The TPS650830 is used for Volume systems with the low voltage rails merged for the smallest footprint
and lowest cost system power solution.
The TPS650830 can provide the complete power solution based on the 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 four VR
controllers. An I²C interface allows simple control by the embedded controller (EC). Each version is
available in a 7x7 NFBGA package and a 9x9 NFBGA package. The 7x7 NFBGA package can be used in
Type 4 PCB boards for the smallest area implementation. The 9x9 NFBGA package can be used in Type
3 and Type 4 PCB boards allowing to minimize cost and area.
