The RT7263EZQW is a 3A, 21V, 500KHz synchronous step-down converter in 14 pin WDFN package. The RT7263E is a synchronous step-down regulator with an internal power MOSFET. It achieves 3A of continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. An adjustable soft-start reduces the stress on the input source at start-up. The RT7263E requires a minimal number of readily available external components, providing a compact solution. Typical applications include distributive power systems, battery charger, DSL modems and pre-regulator for linear regulators.
