The ON/OFF control used in TinySwitch can generate audio noise in the clamp capacitor and the transformer at certain load conditions. The following simple design steps can be taken to dramatically reduce audible noise at virtually no added cost. 1. Some types of ceramic capacitors used in primary clamp circuitry can be very noisy.

Noise reduction circuit sensitivity can be regulated with potentiometer P1: if it is higher, the more rapidly decreases the noise suppression. In this way, the sensitivity of the circuit can be adapted to different sources of music. The maximum audio signal which circuit can work is 210 mV. Distortion is less than 0.01%.

NE5532N. This audio noise filter circuit is a bandpass filter for audio frequency band. It filters unwanted signals that are lower or higher than the audio frequencies. It has 2 filters: a low pass filter and a high pass filter in a cascade configuration. Both filters are second-order filters with a 24 dB/octave fiter capability.
