GENERAL DESCRIPTION

The ACT8931A is a complete, cost effective, highly-

efficient ActivePMUTM power management solution,

optimized

for

the

unique

power,

voltage-

sequencing, and control requirements of the

Rockchip RK2928/RK2926 processors. It is ideal for a

wide range of high performance portable handheld

applications such as tablet or pad devices. This device

integrates the ActivePathTM complete battery charging

and management system with seven power supply

channels.

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 1100mA of output

current, while the third supports up to 1200mA. All

four low-dropout linear regulators are high-

performance, low-noise regulators that supply up to

320mA of output current.

The ACT8931A is available in a compact, Pb-Free

and RoHS-compliant TQFN55-40 package.
