Description
Reference voltage output. Nominal voltage is 2.5 V.
Clamping maximum duty cycle under normal operation.
Clamping maximum duty cycle under open-lamp condition.
Short-circuit protection input (VTH=0.6V)
Reference voltage input for dimming control.
Current sense feedback.
Compensation for the current sense feedback.
Ground.
Soft-start ensures lamp current pulses gradually increases to its normal
value
