Buck Converter Making Noise at Carl Buteau blog

Buck Converter Making Noise. Unfortunately, i am getting terrible noise on the output. I'm making a buck converter, this is the circuit i've: First step is to optimize (minimize) the area of the high di/dt loop. However, this buck converter makes a weird sizing sound as soon as i connect the arduino. I suspect that this is due to the power. I'm using as a main source a 30v. For buck, the high di/dt loop is formed by the input capacitor and the power. When the 100 hz pwm is enabled (and only when it is enabled), the +3.3 v power supply produces an audible noise which seems to be at the pwm frequency. I have built a buck converter on the ts30011. The average voltage at the output is ok, but i'm getting lot of noise at all nodes of the circuit:
