6 / 23 page Pin Description PIN TQFN TSSOP NAME FUNCTION 1 3 OVP+ LED-String Overvoltage Protection Input. Connect a resistive voltage-divider between the positive output, OVP+, and LV to set the overvoltage threshold. OVP+ has a 1.435V threshold voltage with a 200mV hysteresis. 2 4 SGND Signal Ground 3 5 COMP Error-Amplifier Output. Connect an RC network from COMP to SGND for stable operation. See the Feedback Compensation section. 4 6 REF 3.7V Reference Output Voltage. Bypass REF to SGND with a 0.1µF to 0.22µF ceramic capacitor. 5 7 REFI Current Reference Input. VREFI provides a reference voltage for the current-sense amplifier to set the LED current. 68 SC Current-Mode Slope Compensation Setting. Connect to an appropriate external capacitor from SC to SGND to generate a ramp signal for stable operation.
