一,产品概述(General Description)
The CXLE8729 is a monolithic high voltage switching regulator with PFM that is
specifically designed to operate from a 24V~100V DC supply.
The CXLE8729 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
