The RT7271 is a high efficiency, synchronous step-down DC/DC converter for applications operating from 4.5V to 17V and requiring up to 6A maximum load. The current mode architecture of RT7271 allows the transient response to be optimized. Cycle-by-cycle current limit provides protection against shorted output 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. The low current shutdown mode provides output disconnect, enabling easy power management in battery powered systems.</p>
