This dimming controlled LED driver circuit is designed using LM3409
P-channel MosFET controller for step-down (buck) current regulators.The
LM3409 devices use Constant Off-Time (COFT) control to regulate an
accurate constant current without the need for external control loop
compensation Dimming controlled LED driver electronic circuit require an
input voltage of 36 volts and will provide at output a voltage of 24
volts at a maximum current of 700mA
