Hi,
for a project I need to control 2 independant fans. The manufacturer of the fan does not allow to set the fan speed via a PWM signal on the VCC line (no separate PWM input is provided), but only by varying the DC supply voltage (within a range of 6V to 13V). How can I do this the simplest way?
I thought that the LT3088 LDO in combination with the AD5280 Digital Potentiometer could work, or am I mistaken? Power Consumption/Dissipation is no issue, low radiated and conducted emissions are more important.
