RT7237BHGSP Datasheet PDF - Richtek

●The RT7237BHGSP is a 2A, 18V, 1.2MHz synchronous step-down converter in 8 pin SSOP package. It is a 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 compensation allow the transient response to be optimized over a wide input range and loads. Cycle-by cycle 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 (<3µA) shutdown mode provides output disconnection, enabling easy power management in battery-powered systems.
