STPMIC1L Power Management IC for MPU: 2 Buck Converters and 4 LDOs

The STMicroelectronics STPMIC1L power‑management IC with advanced low‑power features that are managed by a host processor through I²C and general I/O interfaces

Image of STMicroelectronics STPMIC1L Power Management ICThe STMicroelectronics STPMIC1L fully integrated power‑management IC is tailored for STM32MP1x MPU applications that demand low power consumption and high efficiency. It incorporates advanced low‑power features that can be managed by a host processor through I²C and general I/O interfaces.

Its regulators are engineered to deliver power not only to the main application processor but also to external system components such as DDR and Flash memory devices. Additional peripherals and core circuitry are powered through configurable GPO pins.

The device includes two high‑performance buck SMPS regulators, optimized for fast transient response and precise output voltage across a wide range of operating conditions. An advanced PWM phase‑shift synchronization system, supported by an integrated PLL, helps minimize noise and reduce EMI.

Features
  • Input voltage range from 2.8 V to 5.5 V
  • Two buck SMPS converters with adaptive constant on-time (COT) topology
  • Two adjustable general-purpose LDOs
  • One LDO for DDR3L/DDR4 termination (sink-source), or as general-purpose LDO
  • One LDO for USB PHY supply
  • Two MHz switching frequency buck converters with forced PWM
  • User programmable non-volatile memory (NVM), enabling scalability to support a wide range of applications
  • Immediate output alternate settings toggle via dedicated power control pins
  • Programmable output voltages turn-on/off sequences I²C and digital IO control interface
  • Two GPO output controls for external commands
  • VFQFPN 28L (4 mm x 4 mm x 1.0 mm)
Applications
  • Power management for embedded microprocessor units
  • Wearable and IoT devices
  • Portable devices
  • Human machine interfaces
  • Smart home devices
  • Power management unit companion chip for the STM32MP13/15 MPUs
