【文字介紹】

The RT7237A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 2A output current from a 4.5V to 17V input supply. The RT7237A's current mode architecture and external compensation allow the transient response to be optimized over a wide input range and loads. Cycle-bycycle current limit provides protection against shorted outputs, and soft-start eliminates input current surge during start-up. The RT7237A also provides under voltage protection and thermal shutdown protection. The low current (<3μA) shutdown mode provides output disconnection, enabling easy power management in battery-powered systems. The RT7237A is available in an SOP-8 (Exposed Pad) package.
