The TPS659119-Q1 device is an integrated power-management IC dedicated to systems using an applications processor requiring multiple power rails. The device provides three step-down converters, one control for an external converter, eight LDOs, and is designed to be flexible for supporting different processors and applications. Two of the step-down converters provide power for dual-processor cores and support for dynamic voltage scaling by a dedicated I2C interface for optimum power savings. The third converter provides power for inputs and outputs (I/Os) and memory in the system. The control for an external converter can sequence and scale the voltage of an external converter for a high-current rail in the system. All trademarks are the property of their respective owners. The device also includes eight general-purpose LDOs providing a wide range of voltage and current capabilities. Five of the LDOs support 1 to 3.3 V with 100-mV steps, and three LDOs support 1 to 3.3 V with 50-mV steps. All LDOs are fully controllable by the I2C interface. In addition to the power regulators, the device contains nine configurable GPIOs with multiplexing features to support a wide variety of functions. The device also includes an embedded power controller to manage the power sequencing requirements of the system. The power sequencing is programmable by EEPROM.

The TPS65912x device provides four configurable step-down converters with up to 2.5-A output current for memory, processor core, I/O, or preregulation of LDOs. The device also contains ten LDO regulators for external use. These LDOs can be supplied from either a battery or a preregulated supply. Power-up or power-down controller is configurable and can support any power-up or power-down sequences(OTP-based). The TPS65912x device integrates a 32-kHz RC oscillator to sequence all resources during power up or power down. All LDOs and DC-DC converters can be controlled by I2C-SPI interface or basic ENABLE balls. In addition, an independent automatic voltage-scaling interface allows for transitioningDC-DC to a different voltage by I2C or basic Roof/Floor Control. Three RGB LEDs with an advanced dimming feature are integrated inside the device. GPIO functionality is multiplexed with LED/ENABLE/SPI when not used. Each GPIO can be configured as part of the power-up sequence to control external resources. One SLEEP pin enables power mode control between active mode and preprogrammed sleep mode for power optimization. For system control, the TPS65912x device has one comparator for system state management. The TPS65912x device comes in a 9-pin × 9-pin DSBGA package (3.6 mm × 3.6 mm) with a 0.4-mm pitch.
