RT7237B Datasheet | Richtek

® 2A, 18V, 1.2MHz Synchronous Step-Down Converter General Description The RT7237B is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 2A output current from a 4.5V to 18V input supply. The RT7237B's current mode architecture and external pensation 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 RT7237B also provides under voltage protection and thermal shutdown protection. The low current (<3 μ A) shutdown mode provides output disconnection, enabling easy power...
