Description

The MP2358 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. Programmable soft-start minimizes the inrush supply current and the output overshoot at initial startup. The MP2358 requires a minimum number of readily available standard external components.
