The ACT8862 is a complete, cost effective, highlyefficient ActivePMUTM power management solution,
optimized for the unique power, voltagesequencing, and control requirements of the Amlogic
AML8726-M3 processor.
Optimized for Amlogic AML8726-M3 Processor
Three Step-Down DC/DC Converters
Four Low-Dropout Linear Regulators
I2CTM Serial Interface
This device features three step-down DC/DC
converters and four low-noise, low-dropout linear
regulators.
Advanced Enable/Disable Sequencing Controller
Minimal External Components
Tiny 4×4mm TQFN44-32 Package
− 0.75mm Package Height
− Pb-Free and RoHS Compliant
The three DC/DC converters utilize a highefficiency, 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 highperformance, low-noise, regulators that supply up to
80mA, 320mA, 320mA and 320mA, respectively.
The ACT8862 is available in a compact, Pb-Free
and RoHS-compliant TQFN44-32 package.
