LED matrix display experimental circuit board composed of TLD2131

Introduction: The high side LED driving chips TLD2131 and tld2331 of Infineon company are used to form an LED matrix driving circuit together with NPN transistors. A small amount of GPIO can be used to drive LED matrix display. In this paper, three TLD2131 are used to form 3 × The working principle of the circuit is tested. It provid ...
