Product Description
Product Description
The ACT8846 is a complete, cost effective, and
highly-efficient ActivePMUTM power management
solution optimized for the power, voltage
sequencing and control requirements of Rockchip
RK3066 application processor family.
The ACT8846 features four fixed-frequency,
current-mode, synchronous PWM step-down
converters that achieve peak efficiencies of up to
97%. These regulators operate with a fixed
frequency of 2.25MHz, minimizing noise in sensitive
applications and allowing the use of small external
components. These buck regulators supply up to
2.8A of output current and can fully satisfy the
power and control requirements of the multi-core
application processor. Dynamic Voltage Scaling
(DVS) is supported either by dedicated control pins,
or through I2C interface to optimize the energy-pertask
performance for the processor. This device
also include eight low-noise LDOs (up to 350mA
per LDO), one always-on LDO and an integrated
backup battery charger to provide a complete
power system for the processor.
The power sequence and reset controller provides
power-on reset, SW-initiated reset, and power cycle
reset for the processor. It also features the
watchdog supervisory function. Multiple sleep
modes with autonomous sleep and wake-up
sequence control are supported.
The thermal management and protection
subsystem allows the host processor to manage the
power dissipation of the PMU and the overall
system dynamically. The PMU provides a thermal
warning to the host processor when the
temperature reaches a certain threshold such that
the system can turn off some of the non-essential
functions, reduce the clock frequency and etc to
manage the system temperature.
The ACT8846 is available in a compact, Pb-Free
and RoHS-compliant TQFN66-48 package.
