Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Open-collector LED driver output, rated for 0.8V to 30V with an absolute maximum output current of 150mA. |
| 2 | BIAS | input | Biases the open-collector output transistor; supply range is 4.5V to 30V and the absolute maximum BIAS voltage relative to GND is 30V. |
| 3 | EN | input | Enable pin for PWM dimming that provides access to the base of Q2 and the collector of Q1; absolute maximum voltage relative to GND is 6V. |
| 4 | GND | power_in | Ground reference point for setting the LED current. |
| 5 | FB | passive | Feedback pin that should be connected to pin 6 (REXT); absolute maximum LED voltage relative to GND is 6V. |
| 6 | REXT | passive | Current sense pin; the LED current sensing resistor connects from this pin to GND, with an absolute maximum voltage of 6V relative to GND. |
