EUP3468B Dual-Channel CC/CV Mode Synchronous Step-Down Controller DESCRIPTION The EUP3468B is a dual-channel synchronous step-down controller capable of driving 5A continuous load with excellent line and load regulation. The EUP3468B operates in either CC (Constant Current) mode or CV (Constant Voltage) mode with an input voltage range from 8V to 36V. The EUP3468B can be configured as single output or dual outputs with independent programmable CC threshold for current limitation. The EUP3468B 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.
