1.3 Description
The TPS65911x device is an integrated power management IC (PMIC) available in a 98-pin 0.65-mm
pitch BGA package. The TPS65911x 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 LDOs that provide a wide range of voltage and current
capabilities. Five of the LDOs support 1.0 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 LDOs 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.
