APW8855
High Current, High Frequency 7 Outputs Voltage Regulator and Power
Management IC for High Performance Tablet and Ultra Notebook Applica-
1.General Description
3.Features
tions
The APW8855 is a Power Management IC (PMIC) de-
signed to provide 7 Voltage regulators for AMDs Stoney
Ridge APU with ability to communicate via an I2C interface.
The IC operates from a wide input voltage of 5.5V to 20V.
There are 5 Switching Buck regulators and 2 low power
LDOs that are all controlled and sequenced via the serial
interface. The Buck PWM regulators consists of 3 switch-
ing controller driving external power stage such as
APW8703 which is capable of supplying up to 8A supply,
2 single phase switching regulators supplying up to 3A
supply.
The IC is equipped with all the standard protection fea-
tures such as over current, over voltage and internal un-
der voltage lock out protection. The serial interface is an
I2C communication interface which allows supply se-
quencing 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 TQFN4x4-32A
package.
