MA5007 1.2A 1.5MHz Synchronous Buck Converter  GENERAL DESCRIPTION The MA5007 is a monolithic synchronous buck regulator with a built in internal power MOSFET. It achieves 1.2A continuous output current fix switching frequency with excellent load and line regulation. Current mode operation provides fast transient response and eases of loop stabilization. Fault condition protection includes cycle-by-cycle current limiting, output short circuit protection and thermal shutdown. In shutdown mode the regulator draws less than 1μA of supply current. Internal soft-start minimizes the inrush supply current at initial startup. The MA5007 requires a minimum number of readily available standard external components. It is available in SOT23-5L package.  FEATURES - 2.5V to 5.
