I used stc15w104 to control ICN2038S to realize constant current driving of LED. Later I found that STC15W104 was not good and I switched to STC8G1K08A.
ICN2038S is a dual-cache constant current driver chip. The current is adjusted through an external resistor. It uses stc15w104 as the control chip. The LED costs 14.4 yuan per plate and is shipped randomly. ICN2038S costs 0.28 yuan per piece. It is relatively cost-effective. The price has now increased. Unable to use switching power supply, USB power supply can be used
