EUP3452A-2A,30V,300KHz Step-Down Converter  DataSheet
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.
