RT7297B Description
The RT7297B 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 RT7297B's current mode architecture and external pensation allow the transient response to be optimized over a wide input voltage range and loads. Cycleby-cycle current limit provides protection against shorted outputs, and soft-start eliminates input...
