MP9141数据手册MPS中文资料规格书

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.\r
\r
Current mode operation provides fast transient response and eases loop stabilization.\r
\r
Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. In shutdown mode the regulator draws 25μ A of supply current.\r
\r
The MP9141 requires a minimum number of readily available standard external components.
