EUP3489-5A,30V,500KHz Step-Down Converter


EUP3489-5A,30V,500KHz Step-Down Converter DataSheet 

DESCRIPTION

      The EUP3489 is current mode, step-down switching regulator capable of driving 5A continuous load with excellent line and load regulation. The EUP3489 operates with an input voltage range from 4.75V to 30V and the output voltage is externally set from 1.222V to 26V with a resistor divider.
Fault condition protection includes cycle-by-cycle current limit and thermal shutdown. In shutdown mode the regulator draws 3μA of supply current. Internal soft-start minimizes the inrush supply current and the output overshoot at initial startup.
      The EUP3489 require a minimum number of external components.
