Application Information
Connect this pin to the output inductor and Schottky diode.
Connect a 10 nF ceramic capacitor from this pin to SW.
Connect a logic-level PWM signal to this pin to enable/disable the
power FET and reduce the average light output of the LED array.
Connect this pin to system ground.
Set the current through the LED array by connecting a resistor from
this pin to ground.
A resistor connected from this pin to VIN sets the regulator
controlled on-time.
Bypass this pin to ground with a minimum 0.1 μF ceramic capacitor
with X5R or X7R dielectric.
Nominal operating input range is 6V to 42V (LM3402) or 6V to 75V
(LM3402HV).
