Description
Drain of NDMOS switch
Ground (0V)
Multi-function On/Off and brightness control pin:
Connect resistor R
current I
(Note: R
Input voltage (6V to 60V). Decouple to ground with 4.7 F or higher X7R
ceramic capacitor close to device
Leave floating for normal operation.(V
average output current I
Drive to voltage below 0.2V to turn off output current
Drive with DC voltage (0.3V < V
25% to 200% of I
Connect a capacitor from this pin to ground to set soft-start time.
Soft start time increases approximately 0.2ms/nF
