I’m looking for a specific LED driver or circuit…
Main requirements are:
7Vdc Input voltage max
1A LED current minimum
15Vdc Output Voltage minimum
ON / OFF LED control by external pin with to limitations and fast response.
Need to be able to generate fast current pulses in the 10 us range.
Need to be able to have very small pulse time increments (in the nanoseconds range)
So all the LED Drivers with PWM pin that reshapes the PWM signal cannot be used.
I will use an external PWM designed in an FPGA to generate output pulses.
