RT7263B
3A, 21V 500kHz Synchronous Step-Down Converter
General Description
The RT7263B 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 RT7263B requires a minimal number of readily available external components, providing a compact solution.
