The MP1580 is a monolithic step-down switch mode converter with a built in internal power MOSFET. It achieves 2A 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 cycle­by­cycle current limiting and thermal shutdown. In shutdown mode the regulator draws 23μA of supply current. The MP1580 requires a minimum number of readily available standard external components. A synchronization pin allows the part to be driven to 600KHz.
