Detailed Description

6.1

Overview

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.

The Powergood Comparator Logic allows controlling and monitoring up to eight external load switches

within the sequence. All the VR and Load Switch Powergood signals are used in the Powergood Tree of

which the outputs are shown with open-drain outputs. Enable inputs allow connecting externally to set the

sequence, and it also allows using various Sleep Mode State signals. The STANDBYZ allows entering a

Deep Sleep Mode, in which the out put voltages of the voltage regulators can be reduced to save power

by DVS.

The Power Monitoring comparators are used to detect and monitor up to three input power sources

(adapter, battery1, battery2, or any other combination). Over temperature of the PMIC self-protects, and

outputs a Status output, TEMPALERTZ; plus there is a dedicated comparator that can monitor system

over temperature with multiple stacked PTC thermistors, or an NTC thermistor. The PMIC automatically

switches between an internal 3.1-V LDO when a power source is connected; or to a Backup Battery (Coin

Cell) when all power sources are removed. This output RTC rail is used to maintain the always-on RTC

rails for critical register data.
