EUP3454
2A,16V,380KHz Step-Down Converter
DESCRIPTION
The EUP3454 are current mode, step-down switching
regulator capable of driving 2A continuous load with
excellent line and load regulation. The EUP3454 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 EUP3454 require a minimum number of external
components.
