® RT8287A 4A, 21V 500kHz Synchronous Step-Down Converter General Description The RT8287A is a synchronous step-down regulator with an internal power MOSFET. It achieves 4A 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 startup. The RT8287A requires a minimal number of readily available external components, providing a compact solution.
