Specs of LED(BXRA-56C5300H 50W) are 23.5 Vf and 2.1 A typical current.
Led max rated current is 4 A @ 28.5 V only for pusling at 10% duty cycle.
My actual project has 64 such LEDs and will be powered with 24 V 67 A DC supply to 32 such LEDS so equivalent 2.09 A current for each LED string connected in parallel to supply.
I want the LED should be operating at this rated current of 2.1 A for 99% of time and must be able to switch (digitally controllable) must draw 4A with 10% duty cycle and switch back to regular 2.1 A current.
I do have heatsinks for these LEDs as they will be dissipating lot of heat. Can anyone suggest me circuit for this and explain .
