ACT8865 Advanced PMU for Atmel SAMA5D3 Series & SAM9 Series Processors • Three Step-Down DC/DC Converters • Four Low-Dropout Linear Regulators • I2CTM Serial Interface • Advanced Enable/Disable Sequencing Controller • Minimal External Components • Tiny 4x4mm TQFN44-32 Package − 0.75mm Package Height − Pb-Free and RoHS Compliant The ACT8865 is a complete, cost effective, highlyefficient ActivePMUTM power management solution, optimized for the unique power, voltagesequencing, and control requirements of the Atmel SAMA5D3 series SAMA5D[31/33/34/35/36] and SAM9 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 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 320mA. The ACT8865 is available in a compact, Pb-Free and RoHS-compliant TQFN44-32 package.
