| Sep 29, 2017 at 10:47 | comment | added | PlasmaHH | @raforanz: It has a pwm pin | |
| Sep 29, 2017 at 10:43 | comment | added | raforanz | @winny There is no EN pin on chip | |
| Sep 29, 2017 at 10:27 | comment | added | winny | What does the datasheet say? Far from all LED drivers can regulate down to 0 mA, save for forcing EN low. | |
