SWITCHING CHARACTERISTICS
At VCC = 3.0 V to 5.5 V, TA = â40°C to +85°C, CL = 15 pF, RL = 82 â¦, RIREF = 1 kâ¦, and VLED = 5.0 V. Typical values at
VCC = 3.3 V and TA = +25°C, unless otherwise noted.

(1) Output on-time error is calculated by the following formula: TON_ERR (ns) = tOUTON â TGSCLK. tOUTON is the actual on-time of the constant
current driver. TGSCLK is the period of GSCLK.
