PIN DESCRIPTION

VIN is the supply input for the internal logic.

The device is compatible with supply voltages

down to 2.2V and up to 5.5V. A small bypass

ceramic capacitor of 1µF is recommended

between the VIN and GND pins near the

device. The under-voltage lockout (UVLO)

circuitry will place the device into an idle

mode (not switching) whenever the supply

falls below 1.9V.

SW pin is the drain terminal of the internal low

resistance power switch. The inductor and the

Schottky diode anode should be connected to the

SW pin. Traces going to the SW pin should be as

short as possible with minimum loop area. This pin

contains over-voltage circuitry which becomes

active above 24V. In the event of an “Open-Led”

fault condition, the device will enter a low power

mode and the SW pin will be clamped to

approximately 30V.

SHDN* is the shutdown logic input. When the

pin voltage is taken below 0.4V, the device

immediately enters shutdown mode, drawing

nearly zero current. At voltages greater than

1.5V, the device becomes fully enabled and

operational.

FB feedback pin is regulated at 0.3V. A resistor

connected between the FB pin and ground sets

the LED current according to the formula:

I_LED= 0.3V/R1

GND is the ground reference pin. This pin

should be connected directly to the ground

plane on the PCB.

The lower LED cathode is connected to the FB pin.
