STPMIC25 Highly-Integrated Power Management IC

STMicroelectronics' STPMIC25 is a fully integrated power management IC designed for the STM32MP2x MPU’s family applications requiring low power and high efficiency. The device integrates advanced low-power features controlled by a host processor via I²C and IO interface.

The STPMIC25 regulators are designed to supply power to the application processor and external system peripherals, such as DDR, Flash memories, and other system devices.

Seven buck SMPS are optimized to provide an excellent transient response and output voltage precision for a wide range of operating conditions. Very high efficiency in full output load range is achieved thanks to low power (LPM) and high power (HPM) mode selection. All the buck converters are provided with a smooth transition from LPM to HPM. Advanced PWM phase shift synchronization technique with integrated PLL and a programmable spread spectrum frequency modulation reduces EMI.
