® RT7256B 3A, 17V, 1.2MHz Synchronous Step-Down Converter General Description The RT7256B is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.5V to 17V input supply. The RT7256B's current mode architecture and internal compensation allow the transient response to be optimized over a wide input range and loads. Cycle-by-cycle current limit provides protection against shorted outputs, and soft-start eliminates input current surge during start-up. The RT7256B also provides under voltage protection and thermal shutdown protection. The low current (<3μA) shutdown mode provides output disconnection, enabling easy power management in battery-powered systems. The RT7256B is available in an SOP-8 (Exposed Pad) package.
