High speed optocoupler mosfet driver

 · This driver can be used for any duty cycle – all the way from 0% to %. The driving frequency is limited by the speed of the optocoupler. For high frequencies, optically isolated MOSFET drivers may be used instead of the two transistors and the optocoupler – the optically isolated MOSFET driver will be all that’s needed.  · High-speed digital output photocouplers (optocouplers) are optically coupled high-speed, totem-pole output isolators containing a gallium aluminum arsenide (GaAlAs) LED on the input side and a photo diode and signal processing circuit on the output side in a single chip. These devices can be used in a wide variety of applications including.
