Pin Function
Switch O utput Terminal. Dr ai n of inter nal N-MOSFET.
Ground. The exposed pad must be soldered to a
large PCB and connected to GND for maximum
power dissipation.
Dimming Control Input :
--- Analog signal input for analog PWM dimming.
--- PWM signal input for digital PWM dimming.
Output Current Sense. Sense LED string current with
an external resistor connected between VIN and
SENSE.
Supply Input Voltage.
