MP9141中文资料1.8A Step-Down DC to DC Converter数据手册MPS规格书

描述 Description

The MP9141 is a monolithic step-down switch mode regulator with a built in internal power MOSFET. It achieves 1.8A 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. In shutdown mode the regulator draws 25μ A of supply current.

The MP9141 requires a minimum number of readily available standard external components.
