产品概述 返回TOP
The CXLE8728 is a monolithic high voltage switching regulator with PFM that is specifically designed to operate from a 24V~80V DC supply specifically designed to operate from a 24V~80V DC supply。
The CXLE8728 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.
