Hi
I want to made a DC motor driver. the supply of my Driver is 100volt. I use the LM317 to supply my singnal ICs. I have two IC one for generating PWM singal(ne555) and second is a gate dirver to drive n-channel mosfet.
I connect a 1kohm/5w resistor form supply voltage to input pin of LM317 and generate a 14volt output. when i supply NE555 i can generate PWM sinal for gate driver IC, but when i supply gate driver IC with 14volt supply the amplitude of PWM singnal drop. how should i solve this problem?
