  • STNRG devices are a part of the STNRG family of STMicroelectronics® digital devices designed for advanced power conversion applications.

    The STNRG improves the design of the successful STLUX™ family, now integrated in a wide range of LED driver architectures, to support industrial power conversion applications such as PFC+LLC, interleaved LC DC/DC, interleaved PFC for smart power supplies as well as the full bridge for pilot line drivers for electric vehicles.

    Key Features

    • Up to 6 programmable PWM generators (SMED - “State Machine Event Driven”)
      • 10 ns event detection and reaction
      • Max.1.3 ns PWM resolution
      • Single, coupled and two coupled operational modes
      • Up to 3 internal/external events per SMED
    • 4 analog comparators
      • 4 internal 4-bit references
      • Up to 4 external references
      • Less than 50 ns propagation time
      • Continuous comparison cycle
      • Configurable hysteresis voltage levels
    • ADCs (up to 8 channels)
      • 10-bit precision, with operational amplifier to extend resolution to 12-bit equivalent
