Error-Amplifier Output. Connect an RC network from COMP to SGND for stable operation. See
the Feedback Compensation section.
3.7V Reference Output Voltage. Bypass REF to SGND with a 0.1μF to 0.22μF ceramic
Current Reference Input. V REFI provides a reference voltage for the current-sense amplifier to
set the LED current.
Current-Mode Slope Compensation Setting. Connect to an appropriate external capacitor from
SC to SGND to generate a ramp signal for stable operation.
