Hi Grace!
Thanks for contacting us. There's PMIC from Texas Instruments (TPS659037) that has seven step-down switched-mode power supply (SMPS) regulators and it contains seven general-purpose LDOs... All LDOs and SMPS converters can be controlled by the SPI or I2C interface.
Hope that helps,
Elizabeth
