可能是国产,找到国外网站也有在找它的资料:Has anyone a .pdf etc please for this? It's a Chinese manufactured switchmode/PWM powersupply 'management' IC please? It's a very common by the look device used in 100s of thousands of modules. I cannot find any data for it, block diagram, pinouts etc. Google provides images links to sellers, that's all. Anything appreciated!找到一张引脚功能图,和UC3844电路图比较,但不知道两者具体参数是否相同。
