I have a digital signal with voltage of 3V and frequency of 1.6MHz. How can I increase voltage of this signal to 36V? The signal is generated by PWM feature of esp32.

EDIT: I'm trying to use this signal to feed a piezoelectrical layer which is used to generate cold vapor. That thing consumes 0.5 ampere on 36V which is something about 18 watts. The DC Source is totally customizable but at this stage it is a simple AC to DC adapter.

    \$\begingroup\$ If it is just PWM, the easiest might be to switch a mosfet that has a low enough gate capacitance. But it also depends on the load capacitance, impedance, inductance... please add some more info to your question. \$\endgroup\$

  • \$\begingroup\$ What is your load for the 12V signal? And "A DC source"? What is it? \$\endgroup\$

    \$\begingroup\$ At 1.6Mhz, you will need a fast gate driver for the mosfet, the ESP32 gpio outputs can't source/sink anywhere near the required power to switch the gate on a power mosfet at this rate. Also, piezo drivers for misters have a relatively high Q, they resonate at a particular frequency and the drivers are designed to seek this resonate frequency at their output. If you are planning on varying the frequency by anything more than 1 or 2% you will get very low acoustic output at the transducer. \$\endgroup\$ Commented Feb 9, 2022 at 20:40
