EUP3484 3A, 30V, 340KHz Synchronous Step-Down Converter DESCRIPTION The EUP3484 is a synchronous current mode buck regulator capable of driving 3A continuous load current with excellent line and load regulation. The EUP3484 can operate with an input range 4.5V to 30V and the output can be externally set from 0.925V to 20V with a resistor divider. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. In shutdown mode the regulator draws 1µA of supply current. Programmable soft-start minimizes the inrush supply current and the output overshoot at initial startup. The EUP3484 require a minimum number of external components. FEATURES 3A Output Current 220ns Minimum On Time 35V Input Surge Protection Integrated 160mΩ/110mΩ DMOS Switches 4.
