EUP3453 3A,40V,200KHz Step-Down Converter DESCRIPTION The EUP3453 is current mode, step-down switching regulator capable of driving 3A continuous load with excellent line and load regulation. The EUP3453 operates with an input voltage range from 4.75V to 40V and the output voltage is externally set from 0.92V to 15V with a resistor divider. The output current threshold is programmed by an external resistor. The EUP3453 enters into the CC (constant current) mode when output reaches over current threshold. The OV (over voltage) threshold is programmed by an external resistor divider. The EUP3453 stops switching when output reaches over voltage threshold. Fault condition protection includes secondary cycle-by-cycle current limit and thermal shutdown.
