Description

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 (two 500 mA host USB and one

100 mA USB OTG). Its advanced bypass architecture allows the smooth regulation

of VBUS for USB ports from a battery as well as low-cost consumer 5 V AC-DC

adapters.

4 buck SMPS are optimized to provide an excellent transient response and an output

voltage precision for a wide range of operating conditions, high full range efficiency (η

up to 90%) by implementing a low power mode with a smooth transition from PFM to

PWM and also an advanced PWM synchronization technique with an integrated PLL

for a better noise (EMI performance).
