EUP3468A-Dual-Channel CC/CV Mode Synchronous Step-Down Converter DataSheet
DESCRIPTION The EUP3468A is a dual-channel synchronous step-down converter capable of driving 5A continuous load with excellent line and load regulation. The EUP3468A operates in either CC (Constant Current) mode or CV (Constant Voltage) mode with an input voltage range from 8V to 36V. The EUP3468A can be configured as single output or dual outputs with independent programmable CC threshold for current limitation. The EUP3468A 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. The EUP3468A stops switching when the output reaches over voltage threshold which is set by internal resistor divider. 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 EUP3468A is available in SOP-8 (EP) package.
