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 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.

No Connects (NC) are not internally connected and may be used for pass-thru PCB traces.
