GENERAL DESCRIPTION

The ACT8865 is a complete, cost effective, highly-

efficient ActivePMUTM power management solution,

optimized for the unique power, voltage-

sequencing, and control requirements of the Atmel

SAMA5D2 series ,SAMA5D3 series: SAMA5D

[31/33/34/35/36], and SAM9 series:SAM9G

[15/25/35/45/46]; SAM9X[25/35], SAM9M[10/11],

SAM9N[11/12] processors. It is ideal for a wide range

of high performance portable handheld applications

such as human-machine interfaces, control panels,

smart grid infrastructures, network gateways, M2M

systems, 2D barcode scanners, barcode printers,

machine vision equipment, as well as home and

commercial building automations, POS terminals,

medical devices and white goods.

This device features three step-down DC/DC

converters and four low-noise, low-dropout linear

regulators.

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

320mA.

The ACT8865 is available in a compact, Pb-Free

and RoHS-compliant TQFN44-32 package.
