Cxac85137 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 5W. The chip minimizes the number of system components and uses sop8 packaging, which enables the cxac85137 to reduce the space occupied by the system. Cxac85137 has a high-precision current sampling circuit, which makes the output current accuracy within ?3%. At the same time, cxac85137 has led open / short circuit protection, overcurrent protection, undervoltage protection
