GENERAL DESCRIPTION
The ACT8933 is a complete, cost effective, highly-
efficient ActivePMUTM power management solution,
optimized for the unique power, voltage-
sequencing, and control requirements of the
CoreLogic LUCY processors.
This device features three step-down DC/DC
converters and four low-noise, low-dropout linear
regulators, along with a complete battery charging
solution featuring the advanced ActivePathTM
system-power selection function.
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 supply up to 250mA each.
The ACT8933 is available in a compact, Pb-Free
and RoHS-compliant TQFN55-40 package.
