Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
1. I_reg(SS) steady state is the voltage (Vak) applied for a time duration ≥ 170 sec, using FR−4 @ 1000 mm² 2 oz. Copper traces, in still air.
2. V_overhead = V_in − V_LEDs. V_overhead is typical value for 48% I_reg(SS).
3. I_reg(P) non−repetitive pulse test. Pulse width t ≤ 1 msec.
