Pop Noise Reduction
The FAN7024 contains circuitry to minimize turn-on and shutdown transients or ’clicks and pop’. For this discussion, turn-on
refers to either applying the power supply voltage or when the shutdown mode is deactivated.
To reduce the pop noise, the FAN7024 has some delay. During that delay, the input capacitor is precharged and the normal
operation is prepared. Such delay time can be controlled by choosing C
