TI TPS659119DAIPFPRQ1

The TPS659119-Q1 is an integrated power management IC designed for systems where the hosted application processor requires multiple power rails. The device provides three buck converters, an interface for controlling an external converter, and eight LDOs, offering flexibility to support various processors and applications. Two of the buck converters supply power to dual processor cores and support dynamic voltage scaling via a dedicated I2C interface for optimal power savings. The third converter supplies I/O and memory in the system. The external converter control enables voltage sequencing and regulation of the external converter for high-current rails in the system. The device also includes eight general-purpose LDOs with a wide range of voltage and current capabilities. Five of the LDOs support 1 to 3.3V in 100mV steps, while the other three support 1 to 3.3V in 50mV steps. All LDOs are fully controllable via the I2C interface. In addition to the power regulators, the device contains nine configurable GPIOs with multiplexing capability to support a broad range of functions. An embedded power controller is also included to manage the system's power-up sequencing requirements. Power sequencing is configured via EEPROM.
