EUP3271A CC/CV Mode Synchronous Step-Down Converter DESCRIPTION The EUP3271A is a synchronous step-down converter capable of driving 5A continuous load with excellent line and load regulation. The EUP3271A operates in either CC (Constant Current) mode or CV (Constant Voltage) mode with an input voltage range from 4.5V to 36V. The EUP3271A provides programmable cable compensation by adjusting external resistor divider. External shutdown function can be controlled by pulling COMP pin to a level below 0.14V. Fault protection includes secondary cycle-by-cycle current limit, short circuit protection and thermal shutdown. Internal soft-start minimizes the inrush supply current and the output overshoot at initial startup. The EUP3271A is available in 5mm×5mm TQFN-20 package. FEATURES  4.
