DESCRIPTION
The CM3406 is a monolithic step-down switch mode converter with a built-in internal power MOSFET. It achieves 1.5A 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 CM3406 requires a minimum number of readily available standard external components.
