Cxac85134 is an excellent original edge feedback controller, which integrates multiple protection functions. Cxac85134 works in the intermittent mode of inductive current, which is suitable for the isolated LED constant current power supply with the input voltage of 85vac ~ 265vac and the power of 12W. The chip minimizes the number of system components and uses SOT23-5 package, which makes cxac85134 able to reduce the space occupied by the system. Cxac85134 has a high-precision current sampling circuit, which makes the output current accuracy within ?3%. At the same time, cxac85134 has led open / short circuit protection, overcurrent protection, undervoltage protection,
