EUP3452A
2A,30V,300KHz Step-Down Converter
DESCRIPTION
The EUP3452A is current mode, step-down switching
regulator capable of driving 2A continuous load with
excellent line and load regulation. The EUP3452A can
operate with an input voltage range from 4.5V to 30V
and the output can be externally set from 0.8V to 12V
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 EUP3452A require a minimum number of external
components.
