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.
