Sales Briefcase
  • The STNRG011 embodies a multi-mode (transition-mode and DCM) PFC controller, a high-voltage double-ended controller for the LLC resonant half-bridge, an 800 V-rated startup generator and a sophisticated digital engine, that manage optimal operation of three blocks.

    The device comes in a 20-pin SO package and offers an advanced solution for power-factor-corrected high-efficiency converters supposed to comply with the most stringent energy saving regulations.
    The power system and the control algorithms are managed by an 8-bit core with dedicated fast peripherals (SMED). Optimized digital algorithms together with HW analog IPs are implemented to guarantee a very high performance, BOM optimization and robustness.
    The digital algorithms are stored into an internal ROM memory and all key application parameters can be stored into a device's NVM (non-volatile memory) memory during the production phase allowing wide configurability and calibration.
    The device can also externally communicate through a 2-pin UART, allowing the monitoring function, the black box storing into an external E2PROMand the software patch upload from the external E2PROM.

    Key Features

    • Digital combo multi-mode PFC + time-shift LLC resonant half-bridge controller
    • Onboard 800 V startup circuit, line sense and X-cap discharge compliant with IEC 62368-1, for reduced standby power
    • Enhanced fixed on time multi-mode TM PFC controller with input voltage feedforward, THD optimizer and frequency limitation
    • Complete set of PFC protections
    • Time-shift control of resonant half-bridge
    • Enhanced burst-mode at light load with fast transient response and line adaptive half-bridge brown-out protection
    • Complete set of half-bridge protections
    • Available in SO20 package
