® RT7257A 3A, 18V, 340kH- Synchronous Step-Down Converter General Description The RT7257A 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 RT7257A's current mode architecture and external compensation allow the transient response to be optimized over a wide input range and loads. Cycle-bycycle current limit provides protection against shorted outputs, and soft-start eliminates input current sur
