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 GND 2 Ground pin VDR 3 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. PVIN 4,5 Connection to the FET source SVIN 6 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. LX 7 Connect to the output inductor. This is the P-Channel FET Drain ISET 8 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 Power PAD 9 Can be connected to inductor LX node for a thermal PAD – see Layout suggestions section.
