RT6224D - SynchronousStep-Down Converter

Datasheet Summary

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.

® RT6224D 3A, 18V, 1.4MHz ACOTTMSynchronous Step-Down Converter General 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. Fault conditions also include output under-voltage protection, output over-voltage protection, and thermal shutdown.
