The EUP3462B is a step-down converter capable of driving 3A continuous load with excellent line and load regulation. The EUP3462B operates in either CC (Constant Current) mode or CV (Constant Voltage) mode with an input voltage range from 8V to 32V. The EUP3462B provides programmable cable compensation by adjusting external resistor divider. The EUP3462B stops switching when the output reaches over voltage threshold which is programmed by external resistor divider. Fault protection includes secondary cycle-by-cycle current limit, short circuit protection and thermal shutdown. In shutdown mode the regulator draws 3μA of supply current. Internal soft-start minimizes the inrush supply current and the output overshoot at initial startup.

The EUP3462B is available in SOP-8 package.
