Beschreibung
The RT6255A is a high-efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 5A output current from a 4.5V to 18V input supply.The RT6255A adopts ACOT 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 and thermal shutdown
