The RT6257A/B is a high-efficiency, monolithic
synchronous step-down DC-DC converter that can deliver
up to 6A output current from a 4.5V to 18V input supply.
The RT6257A/B 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.
