RT6224D Description
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 limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up.
