Pin Function
Ground (Return).
Over Voltage Protection (Input): Connect to the output to
clamp the maximum output voltage. A resistor divider from
this pin to ground could be used to raise the OVP level of
the 15V OVP option.
Supply (Input): Input voltage.
Enable (Input): Logic high enables regulator. Logic low shuts
down regulator.
Compensation Pin.
Analog Ground.
Brightness Control (Input): Either an analog (DAC) or filtered
PWM signal can be used. The gain equation is: VFB =
VBRT / 5. This pin should be left open if the brightness
function is not used. In that case, the FB will be set to its
default value of 200mV.
Reference Voltage (Output): This node is equal to the
voltage on the FB pin. A capacitor from REF to ground
should be used to filter the BRT voltage if PWM dimming is
implemented. A capacitor from REF to ground can also be
used to implement a soft-start function. This pin can be left
open if not used.
Feedback (Input): Output voltage sense node. Default value
is 200mV. Connect the cathode of the LED chain to this pin.
Connect current set resistor from this pin to ground.
Switch Node (Output): Internal power BIPOLAR collector.
Ground (Return): Backside pad.
