Hello Group,

I am wanting to make an adjustable current source within the range of 0-100ma using HPWM. It doesn't matter if the driver is on the high or low side of the load. Load resistance is approx. 20 ohms and the nominal supply voltage is 12 volts. The PWM cannot appear at the output - i.e. it must be smooth DC through the load.

There is probably an easy solution but I just can't see it!

Thanks,

Andy
