                  UD24203 Datasheet





                  The UTC UD24203 is a high frequency synchronous rectified

                  step-down switch mode converter with built in internal power

                  MOSFETs. It offers a very compact solution to achieve 2A

                  continuous output current over a wide input supply range with

                  excellent load and line regulation. The UTC UD24203 has

                  synchronous mode operation for higher efficiency over output

                  current load range.

                  Current mode operation provides fast transient response and

                  eases loop stabilization.

                  Full protection features include OCP and thermal shut down.
