3 Multi-function On/Off and brightness control pin:

• Leave floating for normal operation.(VADJ = VREF = 1.25V giving

nominal average output current IOUTnom = 0.2V/RS)

• Drive to voltage below 0.2V to turn off output current

• Drive with DC voltage (0.3V < VADJ < 2.5V) to adjust output current

from 25% to 200% of IOUTnom

• Connect a capacitor from this pin to ground to set soft-start time.

Soft start time increases approximately 0.2ms/nF

5 Connect resistor RS from this pin to VIN to define nominal average

output current IOUTnom = 0.2V/RS

(Note: RSMIN = 0.36⍀ with ADJ pin open-circuit)

X7R ceramic capacitor close to device

Not internally connected. Connect to ground plane to improve thermal
