EUP3410

EUP3410/3411 2A,16V,380KHz Step-Down Converter DESCRIPTION The EUP3410/3411 is a current mode, step-down switching regulator capable of driving 2A continuous load with excellent line and load regulation. The EUP3410/3411 can operate with an input voltage range from 4.5V to 16V and the output can be externally set from 1.2V to 12V with a resistor divider. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. In shutdown mode the regulator draws 25µA of supply current. The EUP3410/3411 requires a minimum number of external components.
