This high current LED driver circuit is designed using LT3743 designed by Linear Technology.
The LT3743 led driver offer high efficiency and require few external components .
The LT3743 supports a wide range of input voltages from 6 volts to 36 volts . The switching frequency of the LT3743 is programmable from 200kHz to 1MHz through an external resistor on the RT pin.
The average current mode controller will maintain inductor current regulation over a wide output voltage range of 0V to (VIN – 2V).
The LT3734 high current LED driver circuit is capable of changing regulated LED current levels within several μs, providing accurate, high speed PWM dimming between two current levels .
