i have set up the circuit, but i do have some problem that i can't figure it out..
please give me some advice on this..
- my frequency requirement is 20khz, i do follow the formula that the data sheet given, base on my oscilloscope, it shown 10khz.. capacitor voltage is 0.01 micro. resistor value is 5.5k ohms.
- when i connect the the potentiometer, i can't adjust the duty cycle at all..
- my circuit output oscilloscope result.
- circuit that i set up
- and datasheet, it content the formula that i use..
please give me some advice on this..
