摘要： In one particular embodiment, an integrated circuit includes a package and a substrate electrically and physically coupled to the package. The package includes a first pin, a second pin, and metallization coupling the first pin to the second pin. The substrate is coupled to the package via the first pin and the second pin. The substrate includes a plurality of power domains and a power control unit. The second pin of the package is coupled to a particular power domain of the plurality of power domains. The power control unit includes logic and a switch, where the switch includes a first terminal coupled to a voltage supply terminal, a control terminal coupled to the logic, and a second terminal coupled to the first pin of the package. The logic selectively activates the switch to distribute power to the particular power domain via the metallization of the package.

摘要： A device is disclosed that includes a first pin to supply power to a first power domain of an integrated circuit, a second pin to supply power to a second power domain of the integrated circuit, a switching regulator and a controller. The switching regulator is coupled to the first pin to provide a first regulated power supply to the first power domain and is coupled to the second pin to provide a second regulated power supply to the second power domain. The controller is coupled to the first pin and to the second pin to selectively reduce current flow to at least the second pin during a low power event.

摘要： Embodiments of the present invention are directed to switched-mode power supply (SMPS) circuits and methods thereof. The SMPS circuit receives information related to a future load change. For example, the information may be received at a decoder (e.g., a serial bus interface (SBI) decoder) from a microprocessor or microcontroller, such as a mobile station modem (MSM). The SMPS circuit may include an analog-to-digital converter configured to sample an output voltage of the SMPS circuit to determine a time when the future load change occurs. The SMPS circuit may further include a transient recovery circuit (TRC) for stabilizing the output voltage based on the received information when the future load change occurs. For example, the TRC calculates a duty cycle used to transition states of switches of the SMPS circuit to compensate for the future load change.
摘要翻译：本发明的实施例涉及开关电源（SMPS）电路及其方法。 SMPS电路接收与未来负载变化相关的信息。例如，可以在诸如移动台调制解调器（MSM）的微处理器或微控制器的解码器（例如，串行总线接口（SBI）解码器）处接收信息。 SMPS电路可以包括被配置为对SMPS电路的输出电压进行采样以确定发生未来负载变化的时间的模拟 - 数字转换器。 SMPS电路还可以包括瞬态恢复电路（TRC），用于在未来负载变化发生时基于所接收的信息稳定输出电压。例如，TRC计算用于转换SMPS电路的开关状态的占空比，以补偿未来的负载变化。
