GENERAL DESCRIPTION
The ACT8865 is a complete, cost effective, highlyefficient
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.
