  • The ST high voltage BST capacitor controller STHVDAC-253MTG is a high voltage digital to analog converter (DAC), specifically designed to control and meet the wide tuning bias voltage requirement of the BST tunable capacitors.

    It provides 3 independent high voltage outputs, thus having the capability to control 3 different capacitors. It is fully controlled through an RFFE serial interface.
    BST capacitors are tunable capacitors intended for use in mobile phone application, and dedicated to RF tunable application. These tunable capacitors are controlled through a bias voltage ranging from 0 to 24 V. The implementation of BST tunable capacitor in mobile phones enables significant improvement in term of radiated performance, making the performance almost insensitive to external environment.

    Key Features

    • Dedicated controller to bias BST tunable capacitors
    • Operation compliant with cellular systems requirements
    • Turbo and glide modes for optimal system performance
    • Integrated boost converter with 3 programmable outputs (from 0 to 24 V)
    • Low power consumption
    • MIPI RFFE serial interface 1,8 V
    • Available in WLCSP for stand-alone or SiP module integration
