    Using a zener to protect a MOSFET?

    I'm looking to use an optocoupler+MOSFET to switch "undefined" DC power sources; the opto I'm looking at is FOD817D and the MOSFET is FDPF55N06. The power sources may range from 5V (USB power) to 24V, but I could see this being used to switch as high as 36V at some point in the future, and...

    Designing a stable and self-regulated halogen light source

    Need Statement (Not a lot of experience with power electronics, apologies). I need to power a low-voltage halogen lamp (OSRAM 64328 HLX, 65W, Nominal voltage 9.8V, 6.6A) with a 230V AC source. Additionally, I need to have the capability to digitally control the powering of this lamp, which I...

    How do I manage voltage regulation for variable input

    Hey all! I'm trying to build an LED frequency counter. My input signal is an LED I'm using as a detector recieving from an output LED on my signal generator. I'm using square wave output to emulate pwm and my circuitry is going to process the signal to output a 5v logic output that can be read...
