具有 3 个降压转换器和 8 个 LDO 的汽车类 1.4V 至 5.5V 电源管理 IC 80-HTQFP
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.

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.
