Great idea for PWM .So I can have dim effect when connect to the power source using Arduino or STM32 MCU to generate PWM pulse.If you are talking about filtering out spikes and transients, that is only a side issue and not a control of voltage like one would see in a voltage regulator. If you are using a red diode you should know the the forward voltage is going to be low and therefore you wouldn't use a boost driver on that diode. If you are using a 490nm diode, you should know the forward voltage is quite high and you would want a boost driver. But, in the end, they are all just current regulators and nothing more. You can add a TTL input for PWM control of the output or and analog control that will vary the current between two set points, but it is still just a current regulator.
