LED power circuit design with minimum driver chips
A general LED driver requires two LED current feedback to provide accurate and continuous current, and sometimes a photocoupler is used to transmit the signal through an insulator. For low-power LED bulbs, there is not enough space to add so many devices. The LED drive circuit introduced here can achieve the above functions with only one device, ensuring overvoltage protection and ensuring the safety and stability of the bulb.

Low-power, LED light bulb drive circuit:
With STMicro's HVLED805, one device can solve these problems and maintain stable output current CC and output voltage CV, eliminating the need for redundant ones. At the same time, it can also provide over-voltage protection to ensure the safety of the bulb.
