I've searched this and other sites for hours and have yet to come up with a simple solution, which might not be as simple as it sounds to me. Time to blatently ask....
I need to control a fluid controlling solenoid in an auto tranny to control line pressure. The ckt. needs to be able to vary the frequency between 20 and 100 Hz (50/50 duty cycle- square wave), source voltage is say 12.5~13.8 VDC, adj. thus said freq. with a potentiometer, and the solenoid requires about 10A of current. Whatta ya have for me?.......
