Note 4:
V IN1 , V IN2 , and V IN3 are shorted together and single input is referred to as V IN .
All units are 100% production tested at T A = +85°C. Limits over the operating range are guaranteed by design.
OUT1, OUT2, OUT3, OUT4, LX1, and LX2 to ground.
When the input voltage is greater than 2.85V (typ), the UVLO comparator trips and the threshold is reduced to 2.35V (typ).
This allows the system to start normally until the input voltage decays to 2.35V.
