The RT7252A/B is a high efficiency, monolithic synchronous step-down DC-DC converter that can operate at 340kHz/800kHz, while delivering up to 2A output current from a 4V to 17V input supply. The RT7252A/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 disconnection, enabling easy power management in battery-powered systems. The RT7252A/B is available in a SOP-8 (Exposed Pad) package.
