Circuit makes PWM fan drive linear with temperature change
Design How-To  
2/23/2005   Post a comment
A good way to reduce acoustic noise in a system is to adjust the cooling-fan speed as a function of temperature. PWM drive is simple and efficient, but it applies a series of pulses to the fan power supply. The result is a slight physical motion of the fan assembly that can cause a moderate increase in fan noise. To minimize this acoustic noise, you can drive the fan with a dc voltage. From the February issue of Planet Analog magazine, Maxim's Kerry Lacanette shows how to linearize the output of
