TPS659113A2ZRC

The TPS659113A2ZRC is an integrated Power Management IC (PMIC) dedicated to applications powered by one Li-Ion or Li-Ion polymer battery cell, 3-series Ni-MH cells or a 5V 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 3.3V with a 100mV step and three (LDO1, LDO2, LDO4) support 1.0 to 3.3V with a 50mV step. All LDOs are fully controllable by the I2C interface.
