STMicroelectronics STPMIC1

14 Output Rails PMIC 4 Adjustable Constant ON Time (COT) buck SMPS converters BOOST with bypass, LDO for memory power supply

The STPMIC1 is a fully integrated power management IC designed for products based on high integrated application processor designs requiring low power and high efficiency. The device integrates advanced low power features controlled by a host processor via I²C and IO interface.

The STPMIC1 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.

The boost converter can power up to 3 USB ports. Its advanced bypass architecture allows the smooth regulation of VBUS for USB ports from a battery.
