DESCRIPTION
Drain of the internal N-Ch MOSFET
switch.
Ground.
Multi-function On/Off and brightness control pin:
• Leave floating for normal operation (VADJ was internal pulled
up) .average output current IOUTnom = 0.1/RS)
• Drive to voltage below 0.4V to turn off output current
• Drive with DC voltage (0.5V < VADJ < 2.5V) to adjust output
current from 0% to 100% of IOUTnom
• Drive with PWM signal from open-collector or open-drain
transistor, to adjust output current. Adjustment range 25% to 100%
of IOUTnom for f>10kHz and 1% to 100% of IOUTnom for f < 500Hz
• Connect a capacitor from this pin to ground to increase soft-start
time.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Recommended Operating Range indicates conditions for which the device is functional, but do not
guarantee specific performancelimits. Electrical Characteristics state DC and AC electrical
specifications under particular test conditions which guarantee specific performance limits. This
assumes that the device is within the Operating Range. Specifications arenot guaranteed for
parameters where no limit is given, however, the typical value is a good indication of device
