No, Mosfet seems to be fine (VSD-0.5V)

Hi, I've 113KHz piezo transducer @113KHz, I'm trying to drive using esp32 PWM. The circuit is like below https://drive.google.com/file/d/1zhKuv2c7sNym4U4FlQH316Y0FW0GAKf_/view?usp=sharing I don't see any signal at the output to the transducer Few more images a) PWM from esp32 https://drive.google.co...

Hi @ ESP_Minatel
From this board linked below, I removed an unknown uC PWM resistor to MOSFET and connected ESP32 PWM Output-113KHz 50% Duty cycle, even with that transducer turns on and no mist effect.

Can I try with varying frequency to check whether at particular freq inside a for loop or so?

I do not have the scope at the moment due to WFH. I've checked voltage using a meter (average) value of 1.75V. At this, I can hear a slow humming sound(turns on) from the Transducer but doesn't produce the vaporize effect. I've changed the duty cycle value from the above code to 10, and even at high...

Thanks,
I've set the duty cycle to 9 for 110KHz(instead of 2.7MHz).
I don't see the transducer turning on.
Circuit of transducer circuit is:

Input Voltage 12V,113KHz Transducer.

I was trying with Arduino IDE

Hi,
I checked with the above code, gives an error: " struct ledc_timer_config_t' has no member clk_cfg

Thank you.

Hi,
Can't MCPWM be used?
