Description
LED Current Sense. When the voltage of CS pin exceeds the internal threshold voltage, the GD
output goes low.
IC Ground.
External MOSFET Gate Drive.
Input Supply Voltage 8V~12V/DC.
No Connection
Status Remember Register. Connect a capacitor to ground. It’s used for internal register during
switch off. The holding time is programmable with this capacitor.
No Connection
