RT7257BLZSP

® RT7257B 3A, 18V, 1.2MHz Synchronous Step-Down Converter General Description The RT7257B is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.5V to 18V input supply. The RT7257B's current mode architecture and external compensation allow the transient response to be optimized over a wide input voltage range and loads. Cycle-by-cycle current limit provides protection against shorted outputs, and soft-start eliminates input current surge during start-up. The RT7257B also provides under voltage protection and thermal shutdown protection. The low current (
