Description
This is a simple led driver based on PT4115. It is made as a quick solution for devices with constant voltage outputs to turn them to the device with constant current outputs. The input voltage between V+ and V- can be 7 - 30V. Output current is 1A but can be adjusted by replacing R1 using I = 0.1 / R1. For more information see the datasheet at https://people.xiph.org/~xiphmont/thinkpad/PT4115E.pdf. You can keep the DIM input open. In this case the output will always be enabled. Note: The device has not been tested yet. Any comment is appreciated.
