3 Description
The TPS659119-Q1 device is an integrated power-
management IC dedicated to systems using an
applications processor requiring multiple power rails.
The device provides three step-down converters, one
control for an external converter, eight LDOs, and is
designed to be flexible for supporting different
processors and applications.
Two of the step-down converters provide power for
dual-processor cores and support for dynamic voltage
scaling by a dedicated I²C interface for optimum
power savings. The third converter provides power for
inputs and outputs (I/Os) and memory in the system.
The control for an external converter can sequence
and scale the voltage of an external converter for a
high-current rail in the system.
