Abstract
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.
