description: The application of constant current circuits is very wide. The following describes several constant current circuits composed of common integrated blocks. Constant current source circuit using switching power supply Constant current source circuit with integrated voltage regulator Constant current source circuit In this paper, the Lingyang 16-bit single-chip microcomputer is used as the control core to realize the numerical control DC current source function. Through this example analysis, I believe everyone will be more clear about the constant current source circuit! 1200 Puffs Vape Pen,Pen Style Atomizer,Pen Atomizer,Vape Pen Atomizer Shenzhen Xcool Vapor Technology Co.,Ltd , http://www.xcoolvapor.com
