hing regulator capable of driving 1.5A continuous load with excellent line and load regulation. The EUP3455 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 EUP3455 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 EUP3455 stops switching when output reaches over voltage threshold. Fault condition protection includes secondary cycle-by-cycle current limit and thermal shutdown.
