UD24203 Datasheet
  

FAST TURN-OFF INTELLIGENT CONVERTER

 

 

DESCRIPTION

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.
