Product overview
Description
The 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 interfaces.
The STPMIC25 regulators are designed to supply power to the application processor as well as to the 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 the full output load range is achieved due to low power mode (LPM) and high power mode (HPM) selection. All the buck converters are capable of a smooth transition from LPM to HPM. The converters use an advanced PWM phase shift synchronization technique with integrated PLL and a programmable spread spectrum frequency modulation to reduce EMI.
