产品概述 返回TOP
The CXLB73115 is a dual-channel synchronous step-down converter capable of driving 5A continuous load with excellent line and load regulation. The CXLB73115 operates in either CC (Constant Current) mode or CV (Constant Voltage) mode with an input voltage range from 8V to 36V. The CXLB73115 can be configured as single output or dual outputs with independent programmable CC threshold for current limitation. The CXLB73115 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 CXLB73115 is available in SOP-8 (EP) package.
