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.
