General Description

The APW8857 is a Power Management IC (PMIC) designed to provide 8 Voltage regulators and 1 Power Switch for AMD’s Raven Ridge APU with ability to communicate via an I2C interface.

The IC operates from a wide input voltage of 6V to 20V.

There are 5 Switching Buck regulators 3 low power LDOs and 1 Power Switch that are all controlled and sequenced via the serial interface.

Key Features

such as over current, over voltage and internal under voltage lock out protection. The serial interface is an I2C communication interface which allows supply sequencing as well as controlled supply ramp up and ramp down of all supplies except for the always on 1.5V LDO supplying to RTC load. The IC is offered in TQFN5x5-40 package. 2.
