RT6224D - SynchronousStep-Down Converter

The RT6224D is a high-efficiency, monolithic synchronous step-down DC-DC converter that can deliver up to 3A output current from a 4.3V to 18V input supply. The RT6224D adopts ACOTTM architecture to allow the transient response to be improved and keep in constant frequency. Cycle-by-cycle current li.
