1. I_reg(SS) steady state is the voltage (Vak) applied for a time duration ≥ 10 sec, using FR−4 @ 300 mm² 1 oz. Copper traces, in still air.
2. V_overhead = V_in − V_LEDs. V_overhead is typical value for 85% I_reg(SS).
3. I_reg(P) non−repetitive pulse test. Pulse width t ≤ 300 msec.
4. f = 1 MHz, 0.02 V RMS.
