Dec 21, 2015 High Speed, High Current Pulsed LED Driver short as ten nanoseconds that can illuminate extremely fast processes, such as fuel injection.
Matshita Ujda340 Driver
I've seen push-pull drivers, but not that work well; they clamp the LED to 0 V which means you have to charge the junction right from zero .

The MAX16818 is the first LED driver controller that enables Maxim's technology for fast LED current transients of up to 20A/µs and 30kHz dimming frequency. This device utilizes average-current-mode control that enables optimal use of MOSFETs with optimal charge and on-resistance characteristics.
The MIC2843 is a six-channel WLED driver. The WLED driver is designed to maintain proper current regulation with LED current accuracy of 1.5% while the typical.
Figure 5 Fast LED driver using operational amplifier with the gain of Vout/Vin = (R1+RF)/R1. Vin has a maximum value of 1V so that the gain should be roughly more than 2.5 in order to light up the diode.
Aug 8, 2016 For the VLC technology, switching type LED driver is a general structure. The LED driver serves as (a) a traditional ultrafast recovery diode.
Ultra-fast LED Flash Unit for Quality Checks February 3, 2010, Siemens Siemens researchers have developed the world’s fastest LED stroboscopic lamp for the purposes of quality control.
Our premium range of LED drivers give long term performance in demanding commercial and retail environments. Refine your search for either 12v or 24v drivers using the search function on the left hand column.
Driving LED in a Nanosecond Regime by a Fast. Operational off an LED. One big advantage if the device is extremely fast response to external signals.

The LED driver previously described has been used as a light source in a FLIM setup. For comparison and validation of the driver’s FLIM capabilities, we used a laser diode. The laser diode used was a Sharp 120 mW GH0781JA2C. We mounted this diode on a ThorLabs TCLDM9, temperature controlled laser diode mount with an external RF input for modulation. The laser diode intensity.
