I want to pump a 2 amp 40 nsec pulse through an IR LED (Vishay TSHF5210) every 10msec or so. I have to keep the driver cheap & simple because I'm cheap & simple. I hope I can find something in an SOIC package since I can't see anything smaller.
I was going to use a MOSFET driven with a MOSFET driver but I notice that MOSFET drivers contain MOSFETS so why bother with the MOSFET that would be driven by the MOSFET driver if I can drive the LED directly with the MOSFET driver.
There are a few MOSFET driver chips that can handle the current and speed that are relatively cheap (< $2). I know it's not the usual application but is there any reason a MOSFET driver can't drive an LED?
Thanks
