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 for AL9910. Can supply up to 1 mA
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.
