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.
