Current sink input. Connect the cathode of the white LEDs to these inputs.
Enable input. A logic high enables the converter, logic low forces the device into shutdown mode reducing the

I
supply current to less than 1 A if EN2 is tied to GND.
An applied PWM signal reduces the LED current as a function of the duty cycle of the PWM signal. EN1 and EN2
can be tied together for PWM dimming between 0 mA and the maximum set with ISET. EN1 and EN2 can also be
