3A, 21V 500kHz Synchronous Step-Down Converter
The RT8288 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 internal soft-start
minimizes external parts count and internal compensation
The RT8288 requires a minimal number of readily available
external components, providing a compact solution.
