RT7298AHGQW Datasheet PDF - Richtek

●The RT7298AHGQW is a 6A, 18V synchronous step-down converter in 14 pin WQFN package. The RT7298A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 6A output current from a 4.5V to 18V input supply. The RT7298A current-mode architecture with external compensation allows the transient response to be optimized over a wide range of loads and output capacitors. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. Fault condition protections include output under-voltage protection, output over-voltage protection and overtemperature protection. The low current shutdown mode provides output disconnection, enabling easy power management in battery-powered systems. Typical applications include high performance point of load regulation, notebook computers and high density and distributed power systems.
