I am trying to create a simple and cheap frequency circuit with a 555 timer to drive a piezoelectric transducer. The transducer I am using calls for a 48v input with 1.66Mhz frequency timing. I've used a CMOS 555 timer to create the frequency (using 2 trim pots to do some testing). I don't have an oscilloscope but my multimeter shows I'm right on track.
Now, I am trying to use a 5v USB cable and I obviously need to boost the voltage to 48v. I'm not sure how or where I should be putting this boost converter, or even if I'm doing this right?
Here's the circuit I'm using for the 555:
Do I just turn the 5v input into 48v input? or do I have to boost it after the output from the 555?
When I measure the voltage with the multimeter (in place of the crystal) I am getting 1.4v. Obviously not enough to drive the piezo element.
