RT8297B Datasheet | Richtek

® RT8297A/B 1.5A, 17V, 340/800k Hz Synchronous Step-Down Converter General Description The RT8297A/B is a high efficiency, monolithic synchronous step-down DC-DC converter that can operate at 340k Hz/800k Hz, while delivering up to 1.5A output current from a 4V to 17V input supply. The RT8297A/B's current mode architecture allows the transient response to be optimized. 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. The low current (<5μA) shutdown mode provides output disconnect, enabling easy power management in battery-powered systems. The RT8297A/B is available in a WDFN-8L 2x2 package.
