4A, 21V 500kHz Synchronous Step-Down Converter

General Description

The RT8288A 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 internal soft-start

minimizes external parts count and internal compensation

circuitry.

The RT8288A requires a minimal number of readily

available external components, providing a compact

solution.
