Note 1: Guaranteed by minimum and maximum duty-factor tests.
Note 2: The following equation can be used to calculate FB accuracy for output voltages other than 1.232V:
(see Feedback Voltage vs. Load Current)
V FB = V FB (NOMINAL) - (Line Reg) (V OUT / V IN - 0.23) / 0.77 - ( ? Load Reg ? )(I OUT + 0.5 · I RIPPLE ) / I MAX
where: Line Reg = the line regulation
Load Reg = the load regulation
I RIPPLE = (1- V OUT / V IN ) · V OUT / (f OSC · L) where L is the inductor value
I MAX = 250mA (LIM = GND) or 600mA (LIM = IN)
Note 3: Specifications to -40°C are guaranteed by design, not production tested.
