MP2305概述：2A, 23V，340KHZ转换器同步整流Step-Down
The MP2305 is a monolithic synchronous buck regulator. The MP2305 integrates 130mΩ MOSFETS that provide 2A continuous load current over a wide operating input voltage of 4.75V to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit.  MP2305 An adjustable soft-start prevents inrush current at turn-on. MP2305 Shutdown mode drops the supply current to 1μA.  This MP2305, available in an 8-pin SOIC package, provides a very compact system solution with minimal reliance on external components.
