Good afternoon,
Is it possible to dim the LED output of the K8071 kit using a 0-100% pwm supply or by feeding a signal into a section of the circuit? I have tried on a complete module VM143/3, but the LEDs maintained brightness as the module increased the current drive to compensate for the decrease in voltage. Would the VM143/1W version be better? I am driving 3 x 1W leds in series, LED spec 3.3Vf, Imax 700mA. LEDs most efficient at 350mA.
Thanks
