Overview
® RT7264A 4A, 21V, 500kHz Synchronous Step-Down Converter General Description The RT7264A 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 RT7264A requires a minimal number of readily available external components, providing a compact solution.
