Eutech Microelectronics EUP3270
The EUP3270 is a synchronous step-down converter capable of driving 4A continuous load with excellent line and load regulation. The EUP3270 operates in either CC (Constant Current) mode or CV (Constant Voltage) mode with an input voltage range from 4.5V to 30V. The EUP3270 provides programmable cable compensation by adjusting external resistor divider.| Part No. | EUP3270 |

DESCRIPTION
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 EUP3270 is available in SOP-8 (EP) package.FEATURES
