Cxle8333 is a high precision, high efficiency and high power factor step-down LED constant current drive control switch. Working in the critical conduction mode the constant current

Cxle8333 is a high precision, high efficiency and high power factor step-down LED constant current drive control switch. Working in the critical conduction mode, the constant current accuracy can reach ?5% and PF value is greater than 0.9 in the input voltage range of 85vac ~ 265vac. Cxle8333 is mainly suitable for the highlighted buck LED driver, which can achieve constant output current. There are few peripheral devices and low cost of the scheme. It has the characteristics of output on-off and short-circuit protection. It can pass EFT, lightning surge and other reliability tests
