The ACT8847 is a complete, cost effective, and

power management

solution optimized for the power, voltage

sequencing and control requirements of Samsung

Exynos 4210 (S5PC210/S5PV310) and other

application processors. (Please See Ordering

Information Section and its Appendix.)

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-per-

task 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

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 ACT8847 is available in a compact, Pb-Free
