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.
