(Note: R
Input voltage (7V to 30V). 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
Drive with PWM signal from open-collector or open-drain transistor, to
adjust output current. Adjustment range 25% to 100% of I
f>10kHz and 1% to 100% of I
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)
