Step Description Notes

1 Connect a constant current power supply to VLED and PGND. The The supply current I

is set to 1.75A, with a maximum

VIN terminal can be connected to VLED, or another voltage source output voltage of 48 V.

ranged from 6 V to 70 V.

2 Connect five LED strings from VLED to LED1 to LED5 terminals. Each LED string consists of 14 LEDs with a forward

string voltage of lower than 48 V at 0.35A.

3 Turn on the power supply. The five LED strings are turned on and The voltage on R11-R51 is 0.35 V.

the current is 0.35A each.
