Alpha and Omega Semiconductor has introduced the new AOS Digital Controller product portfolio “AOZ97774QE” which provides DC/DC power conversion from the 12V power rail to Point-of-Load voltage for all main subsystems of the 5G wireless network, including CU, DU, and RU platforms. The AOZ97774QE controller is offered in a QFN 5mm x 5mm package and is specifically designed to meet the specifications of the Intel VR13 infrastructure applications. Moreover, this device supports the high accuracy IMON/TMON input for use with AOS or Smart Power Stages (SPS).


The AOZ97774 controller offers up to 15 stored pin-strapped configurations and NVM configuration, with 1,000 times read/write capability for maximum flexibility. This controller is powered by a single 3.3V supply and provides output voltage with 0.5% accuracy. AOS’s proprietary Digital COT architecture provides ultra-fast load transient response and enables stable and low voltage ripple operation with small-sized ceramic capacitors, further reducing solution size and cost.
