Cxle8402 is a high-performance primary side feedback control power switch chip applied to off-line low-power AC / DC switching power supply. It can achieve high-precision constant current output

Cxle8402 is a high-performance primary side feedback control power switch chip applied to off-line low-power AC / DC switching power supply. It can achieve high-precision constant current output within the full voltage input range, with accuracy less than ?5%, without loop compensation, and can save optocoupler, TL431, transformer auxiliary winding and other components and reduce costs. In order to improve the reliability of the system, some protection functions are integrated in the chip, such as cycle by cycle peak current limitation, output on / short-circuit protection and soft start-up
