Advanced PMU for Amlogic AML8726-M3 Processor  
Amlogic AML8726-M3 processor. It 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  
Four Low-Dropout Linear Regulators  
Integrated ActivePathTM Charger  
I2CTM Serial Interface  
Advanced Enable/Disable Sequencing Controller  
Minimal External Components  
Tiny 5×5mm TQFN55-40 Package  
0.75mm Package Height  
Pb-Free and RoHS Compliant  
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 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  
80mA, 320mA, 320mA, 320mA, respectively.  
GENERAL DESCRIPTION  
The ACT8942 is a complete, cost effective, highly-  
efficient ActivePMUTM power management solution,  
optimized for the unique power, voltage-  
sequencing, and control requirements of the  
The ACT8942 is available in a compact, Pb-Free  
and RoHS-compliant TQFN55-40 package.
