1.3 Description
The TPS65911 device is an integrated power management IC (PMIC) available in a 98-pin 0.65-mm pitch
BGA package. The TPS65911 device is dedicated to applications powered by one Li-Ion or Li-Ion polymer
battery cell, 3-series Ni-MH cells, or a 5-V input, and applications that require multiple power rails. The
device provides three step-down converters, one controller for external FETs to support high current rail,
eight LDOs, and the device is designed to be a flexible PMIC for supporting different processors and
applications.
Two of the step-down converters provide power for dual processor cores and support dynamic voltage
scaling by a dedicated I2C interface for optimum power savings. The third converter provides power for the
I/Os and memory in the system.
The device includes eight general-purpose LDO regulators that provide a wide range of voltage and
current capabilities. Five of the LDO regulators support 1 to 3.3 V with a 100-mV step and three (LDO1,
LDO2, LDO4) support 1.0 to 3.3 V with a 50-mV step. All LDO regulators are fully controllable by the I2C
interface.
In addition to the power resources, the device contains an EPC to manage the power sequencing
requirements of systems and an RTC. Power sequencing is programmable by EEPROM.
