40V, 3A, 220kHz Asynchronous Step-Down Converter - AN6523

The AN6523 is a monolithic step-down switch mode converter with a built-in high-side power MOSFET. It achieves 3A 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. The AN6523 is available in an SOP8-EP package, provides a very compact system solution and good thermal conductance.
