STPMIC2LAPQR [STMicroelectronics]

The STPMIC2L is a fully integrated power management IC designed for the STM32M2x MPU series applications requiring low power and high efficiency.

The device integrates advanced low-power features controlled by a host processor via I²C and I/O interfaces.

The STPMIC2L 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.

Three buck SMPS are optimized to provide excellent transient response and output voltage precision for a wide range of operating conditions. The converters use an advanced PWM phase shift synchronization technique with integrated PLL and a programmable spread-spectrum frequency modulation to reduce EMI.
