                  UD05205 Datasheet
                   2.0A 1.5MHZ SYNCHRONOUS BUCK CONVERTER






                  The UTC UD05205 is a monolithic synchronous buck regulator

                  with a built in internal power MOSFET. It achieves 2A continuous

                  output current fix switching frequency with excellent load and line


                  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.




                  * 2.5V~5.5V input voltage range

                  * Up to 2A Output Current

                  * 150/120m? Internal Power MOSFET Switch

                  * Stable with Low ESR Output Ceramic Capacitors

                  * Up to 95% Efficiency

                  * Less than 1μA Shutdown Current

                  * 1.5Mhz Switching Frequency

                  * Thermal Shutdown Protection

                  * Current limit and short circuit protections.

                  * Output Adjustable from 1V to VIN

                  * Build-in soft start function
