STPMIC25APQR PMIC
The STPMIC25APQR is a highly integrated power management IC (PMIC) from STMicroelectronics, specifically designed to supply power to modern microprocessor units (MPUs) and their peripheral systems. It is housed in a 56-pin WFQFN (6.5 x 6.5 x 0.9 mm) package and operates from a wide input voltage range of 2.8V to 5.5V, making it suitable for various battery-powered and regulated input applications.
This PMIC features a comprehensive set of power rails, including 7 high-efficiency buck switching regulators based on an adaptive constant-on-time (COT) topology for fast transient response, 6 adjustable general-purpose LDOs, 1 LDO dedicated for DDR3L/DDR4 memory termination (supporting sink-source operation), 1 LDO for USB PHY supply with automatic power source detection, and 1 reference voltage LDO for DDR memory. Key highlights include a high switching frequency of 2 MHz for the buck converters (with spread spectrum option to reduce EMI), user-programmable non-volatile memory (NVM) for flexible output voltage and sequencing configuration, dedicated power control pins for immediate output setting toggling, and both I²C and digital I/O control interfaces for system management.
AlternativePower Management ICList
● STPMIC25BPQR: A variant in the same family with a different default programming option for the BUCK4 output voltage (e.g., 1.8V VIO instead of 3.3V), offering flexibility for specific processor core voltage requirements.
● STPMIC25DPQR: Another variant with additional programming options enabled (e.g., LDO7/8 enabled and boot from SD-Card configuration), providing a pre-configured solution for specific system boot and peripheral power needs.
● MAX77650: A Maxim Integrated (Analog Devices) highly integrated PMIC for wearable and portable applications, offering a multi-rail power solution with a different feature set and package footprint.
● DA9063: A Dialog Semiconductor PMIC designed for advanced application processors, featuring multiple buck and LDO regulators with dynamic voltage scaling, serving as a functional alternative for complex SoC power management.
