I want to interface 12 VDC rated WS2815B addressable LED strip with a 3.3 VDC microcontroller.
I am having difficulty finding a logic level shifter which translates 3.3 V to 12 V. Data rate is significantly high and hence fast rise and fall times are required. Timings are as below:
How do I tackle this problem?
Two things come to my mind:
1) Maybe there is a part which will do the job and I am not aware of it.
2) I need to implement logic level conversion circuit using basic components. - In this regard, I cam across some circuits as shown below:
However on further reading, I found that these circuits can't achieve the fast rise and fall times required by ws2815b. Is there a better way which can solve my problem?
