Regulator feedback input. A current setting resistor is connected to LED’s cathode and
FB on one side and to ground on the other side. This pin can be also used for dimming
control. By connecting a diode between this pin and a >2V signal the LED can be pulsed
at up to 1kHz
Ground pin
Power supply for the internal driver. This voltage is internally regulated to about 5V
below VIN. Place a 0.1uF decoupling capacitor between VDR and Vin as close as
possible to the IC.
Connection to the FET source
Input power supply for the regulator. Place input decoupling capacitor as close as
possible to this pin. This is the Vin connection for the regulator and is not tied to the
high-side FET.
Connect to the output inductor. This is the P-Channel FET Drain
This pin is used as a current limit input for the internal current limit comparator.
Connect to LX through an optional resistor. Internal threshold is pre-set to 350mV
nominal and can be decreased by changing the external resistor based on the following
formula: VTRSHLD = 350mV – 33uA * R
Can be connected to inductor LX node for a thermal PAD – see Layout suggestions
section.
