      RT8290 詳細介紹

      RT8290概述3A,23V,340kHz同步整流降壓DC-DC
      The RT8290 is a high efficiency synchronous step-down DC/DC converter that can deliver up to 3A output current from 4.5V to 23V input supply. The RT8290's current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. RT8290 Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. The RT8290 also provides output under voltage protection and thermal shutdown protection. The RT8290 low current (<3μA) shutdown mode provides output disconnection, enabling easy power management in battery-powered systems. The RT8290 is available in an SOP-8 (Exposed Pad) package.
