RT7257E Preliminary 3A, 17V, 340kHz Synchronous Step-Down Converter General Description Features The RT7257E 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 RT7257E's current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. Cycle-by-cycle current limit provides protection against shorted outputs, and soft-start eliminates input current surge during start-up. The RT7257E provides thermal shutdown protection. The low current (
