TYPICAL APPLICATIONS
4.1
Reducing Switching Noise
For fans consuming more than 300mA, a slowdown
capacitor (C
SLOW
) is recommended for reducing
switching PWM induced noise (see Figure 4-1). The
value of this capacitor should be 4.7
μ
F to 47
μ
F,
depending on the fan current consumption.
See Application Note AN771 “Suppressing Acoustic
Noise in PWM Fan Speed Control Systems” for more
information.
