Hot-selling and scarce ACT8941AQJ465-T Advanced PMU for Rockchip RK2906/RK2918 Processor QFN spot stock

Product Descriptions

The ACT8941A is a complete, cost effective, highlyefficient ActivePMUTM power management solution,  optimized for the unique power, voltagesequencing, and control requirements of the Rockchip RK2906/RK2918 processor. It is ideal for a  wide range of high performance portable handheld  applications such as tablet or pad devices. This device  integrates the ActivePathTM complete battery charging  and management system with seven power supply  channels.

This device features three step-down DC/DC  converters and four low-noise, low-dropout linear  regulators, along with a complete battery charging  solution featuring the advanced ActivePathTM system-power selection function.

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 1100mA of output  current, while the third supports up to 1200mA. All  four low-dropout linear regulators are highperformance, low-noise regulators that supply up to  320mA of output current.

The ACT8941A is available in a compact, Pb-Free  and RoHS-compliant TQFN55-40 package.
