TYPICAL APPLICATIONS
Reducing Switching Noise
For fans consuming more than 300 mA, a slowdown
capacitor (C SLOW ) is recommended for reducing
switching PWM induced noise (see Figure 5-1). The
value of this capacitor should be 4.7 μF to 47 μF,
depending on the fan current consumption.
See Application Note 771, “Suppressing Acoustic
Noise in PWM Fan Speed Control Systems”
(DS00771), for more information.
