Overview

® RT8287 3A, 21V 500kHz Synchronous Step-Down Converter General Description The RT8287 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 startup.
The RT8287 requires a minimal number of readily available external components, providing a compact solution.
