Description
Drain of NDMOS switch
Ground (0V)
Multi-function On/Off and brightness control pin:
? Leave floating for normal operation.(V ADJ = V REF =1.25V giving nominal average output current
I OUTnom =0.1/R S )
? Drive to voltage below 0.2V to turn off output current
? Drive with DC voltage (0.3V<V ADJ <2.5V) to adjust output current from 25% to 200% (?) of I OUTnom
? Drive with PWM signal from open-collector or open-drain transistor, to adjust output current.
Adjustment range 25% to 100% of I OUTnom for f>10kHz and 1% to 100% of I OUTnom for f<500Hz
? Connect a capacitor from this pin to ground to increase soft-start time. (Default soft-start time=0.5ms.
Additional soft-start time is approx.0.5ms/nF)
Connect resistor R S from this to V IN to define nominal average output current I OUTnom =0.1/R S
(Note: R SMIN =0.27V with ADJ pin open circuit)
Input voltage (7V to 30V). Decouple to ground with 1μF of higher X7R ceramic capacitor close to
