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 sufficient storage capacitor is used to
provide storage when the rectified 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.
