    My goal is to drive an infrared LED like ([this SFH 4727AS](https://dammedia.osram.info/media/resource/hires/osram-dam-5723342/SFH%204727AS_EN.pdf)) to control IR remote controlled devices (for example a TV).\n
    \n
    I can already output the signal on a pin of my microcontroller. The signal has a carrier frequency of 38kHz.\n
    \n
    I am however limited to a 5V 1A power supply and would like to drive the LED as close to the 5W psu limit as possible.\n
    \n
    I first thought about using a MOSFET like [this AO3400A](https://aosmd.com/sites/default/files/res/data_sheets/AO3400A.pdf) together with a resistor, but decided it was worth using an LED driver, do you agree?\n
    \n
    Now I’m looking at [this PAM2804](https://www.diodes.com/assets/Datasheets/PAM2804.pdf) constant current LED driver but I’m not sure if I can just supply my signal to the EN pin. The EN pin is meant for PWM-dimming, so does that mean the output is smoothed to prevent flickering?\n
    \n
    I’d love to hear your thoughts about how I should go about this. Thanks

  +title: "Can I switch this constant current LED driver at 38kHz?"
  +url: null
  +body: """
    My goal is to drive an infrared LED like ([this SFH 4727AS](https://dammedia.osram.info/media/resource/hires/osram-dam-5723342/SFH%204727AS_EN.pdf)) to control IR remote controlled devices (for example a TV).\n
    \n
    I can already output the signal on a pin of my microcontroller. The signal has a carrier frequency of 38kHz.\n
    \n
    I am however limited to a 5V 1A power supply and would like to drive the LED as close to the 5W psu limit as possible.\n
    \n
    I first thought about using a MOSFET like [this AO3400A](https://aosmd.com/sites/default/files/res/data_sheets/AO3400A.pdf) together with a resistor, but decided it was worth using an LED driver, do you agree?\n
    \n
    Now I’m looking at [this PAM2804](https://www.diodes.com/assets/Datasheets/PAM2804.pdf) constant current LED driver but I’m not sure if I can just supply my signal to the EN pin. The EN pin is meant for PWM-dimming, so does that mean the output is smoothed to prevent flickering?\n
    \n
    I’d love to hear your thoughts about how I should go about this. Thanks
