The TPS65911 is an integrated power management IC available in 98-pin 0.65-mm pitch BGA package and dedicated to applications powered by one Li-Ion or Li-Ion polymer battery cell or 3-series Ni-MH cells or a 5-V input, and which require multiple power rails. The device provides three step-down converters, one controller for external FETs to support high current rail, eight LDOs, and is designed to be 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 providing a wide range of voltage and current capabilities. Five of the LDOs support 1.0 to 3.3 V with 100-mV step and three (LDO1, LDO2, LDO4) support 1.0 to 3.3 V with 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.
