DESCRIPTION
The MP2361 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 protections include cycle-by-cycle current limiting and thermal shutdown. In shutdown mode the regulator draws 20µA of supply current. Programmable soft-start minimizes the inrush supply current and the output overshoot at initial startup.
The MP2361 requires a minimum number of readily available standard external components.
