Function

Drain of NDMOS switch

Ground (0V)

Multi-function On/Off and brightness control pin:

• Leave floating for normal operation.(VADJ = VREF = 1.25V giving nominal average output current

o IOUTnom = 0.1/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 increase soft-start time.

• Soft-start time increases approximately 200µs/nF.

Connect resistor RS from this pin to VIN to define nominal average output current IOUTnom = 0.1/RS

(Note: RSMIN = 0.1Ω with ADJ pin open circuit)

Input voltage (6V to 60V). Decouple to ground with 4.7µF of higher X7R ceramic capacitor close to device.
