GENERAL DESCRIPTION
The ACT8892 is a complete, cost effective, highly-
efficient ActivePMUTM power management solution
that is ideal for a wide range of high performance
portable handheld applications such as tablet or pad
devices.
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 1150mA of output
current, while the third supports up to 1300mA. All
four low-dropout
linear
regulators
are
high-
performance, low-noise, regulators that supply up to
320mA.
The ACT8892 is available in a compact, Pb-Free
and RoHS-compliant TQFN44-32 package.
