APW8858
Wide Input 5.4V to 21V Power Management IC(PMIC) for High Performance Com-
puting Applications
1.General Description
The APW8858 is a Power Management IC (PMIC) de-
signed to provide complete Power Management solution
for Intel GLK(*) plateform 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
APW8858 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
VCCRAM, Two LDOs for variety of applications such as
memory VTT and VPP(V25U), Tow internal high frequency
3A Buck regulators typically used for 1.8V and 1.2V sup-
ply and One load switch(V18U). 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 fea-
tures such as over current, over voltage and internal un-
der 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 dis-
charge and IRQ.
The IC is offered in a small TQFN, 5x5-40L package for
best thermal performance while optimizing the cost.
