GENERAL DESCRIPTION
The ACT8895 is a complete, cost effective, highly-
efficient ActivePMUTM power management solution,
optimized for the unique power, voltage-
sequencing, and control requirements of the SiRF
PrimaTM and Atlas IVTM processors.
This device features three step-down DC/DC
converters and four low-noise, low-dropout linear
regulators.
The three DC/DC converters utilize a high-
efficiency, fixed-frequency (2MHz), current-mode
PWM control architecture that requires a minimum
number of external components. Two DC/DCs are
capable of supplying up to 900mA of output current,
while the third supports up to 700mA. All four low-
dropout linear regulators are high-performance,
low-noise, regulators that each supply up to 150mA.
The ACT8895 is available in a compact, Pb-Free
and RoHS-compliant TQFN55-32 package.
