Description
Input voltage 8V to 450V DC
Senses LED string current
Device ground
Drives the gate of the external MOSFET
Low Frequency PWM Dimming pin, also Enable input. Internal
100kΩ pull-down to GND
Internally regulated supply voltage (7.5V nominal). Can supply
up to 1mA for external circuitry. A suffi cient storage capacitor is
used to provide storage when the rectifi ed AC input is near the
zero crossings.
Linear dimming by changing the current limit threshold at current
sense comparator
Oscillator control. A resistor connected between this pin and
ground sets the PWM frequency.
