一,产品概述(General Description) ![]()
The CXLE8614 is a monolithic high voltage switching regulator with
PFM that is specifically designed to operate from a 24V~100V DC supply.
The CXLE8614 is a high efficiency LED driver switching regulator.
The LED string is driven at DC constant current rather than constant
voltage, thus providing constant current output and enhanced reliability.
