Description:

The STPMIC1 is a fully integrated power management IC designed for productsbased on high integrated application processor designs requiring low power and highefficiency.The device integrates advanced low power features controlled by a host processorvia I²C and IO interface.The STPMIC1 regulators are designed to supply power to the application processoras well as to the external system peripherals such as: DDR, Flash memories andother system devices.The boost converter can power up to 3 USB ports (two 500 mA host USB and one100 mA USB OTG). Its advanced bypass architecture allows the smooth regulationof VBUS for USB ports from a battery as well as low-cost consumer 5 V AC-DCadapters.4 buck SMPS are optimized to provide an excellent transient response and an outputvoltage precision for a wide range of operating conditions, high full range efficiency (ηup to 90%) by implementing a low power mode with a smooth transition from PFM toPWM and also an advanced PWM synchronization technique with an integrated PLLfor a better noise (EMI performance).
