MP1580数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

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 cycle?y?ycle current limiting and thermal shutdown. In shutdown mode the regulator draws 23? 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.
