APW8856
Wide Input 5.4V to 21V Power Management IC(PMIC) for High Performance
Computing Applications
1. General Description
The APW8856 is a Power Management IC (PMIC) de-
signed to provide complete Power Management solution
for the Rest of the Platform Power (ROP) supplies for
Intel Canon Lake(*) applications. The IC operates from a
single supply voltage of 5.4V to 21V allowing it to be used
in 2 Cell to 4 Cell battery applications. The APW8856 is
designed to provide maximum number of regulators in the
smallest available cost effective package. Included in the
IC are; Four Switching Buck controllers for 5V and 3.3V
system voltages as well as VDDQ and 1.05V, Six LDOs for
variety of applications such as memory VTT and Vpp, One
internal high frequency 3A Buck regulator typically used for
1.8V supply and One Dual Input Single output switch. The
PWM controllers use the ANPEC cost effective external
Power Blocks APW870x family for minimum pin interface
with the PMIC, while providing output currents of up to 25A
capability.
The IC is equipped with all the standard protection features
such as over current, over voltage and internal under
voltage lock out protection as well as thermal SD.
The serial interface is an I2C communication interface
which allows supply sequencing as well as controlled
margining of ramp up and ramp down of all supplies to
optimize battery power consumption. The I2C interface
also allows for adjustability of Soft Start, Forced PWM/Auto
PFM/PWM, power sequencing as well output discharge
and IRQ.
The IC is offered in a small TQFN, 5x5-40L package for
best thermal performance while optimizing the cost.
