2A, 18V, 800kHz Synchronous Step-Down Converter
The RT7247C is a high efficiency, monolithic synchronous step-down DC/DC ,converter that can deliver up to 2A output current from a 4.5V to 18V input ,supply. The RT7247C's current mode architecture and external 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 RT7247C 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 RT7247C is available in an SOP-8 ,(Exposed Pad) package.
